Indian StandardSPECIFICATION FOR

COPPER OXYCHLORIDE, TECHNICAL

(Second Revision)

o. FOR E WO R D

0.1 This Indian Standard (Second Revision) was adopted by theIndian .Standards Institution on 31 August 1978, after the draft finalizedby the Pest Control Sectional Committee had been approved by theAgricultural and Food Products Division Council and Chemical DivisionCouncil.

0.2 Copper oxychloride is extensively used for agricultural and horti­cultural purposes in fungicidal formulations.

0.3 Copper oxychloride is the common name for basic cupric chlorides.

0.4 This standard was first issued in 1959. This was revised in 1969 toincorporate improved requirement for total soluble alkalinity andspecifying soluble copper salts in view of the better manufacturingtechnique becoming available. This revision has been taken up to bringit in alignment with the requirements as stipulated by Central Insecti­cides Board ( CIB ).

0.5 In the preparation of this standard due consideration has been givento the provisions of the Insecticides Act, 1968 and the Rules framedthereunder. However, this standard is subject to the restrictions imposedunder these, wherever applicable.

0.6 For the purpose of deciding whether a particular requirement ofthis standard is complied with, the final value, observed or calculated,expressing the result of a test or analysis, shall be rounded off inaccordance with IS : 2-1960*. The number of significant places retainedin the rounded off value should be the same as that of the specifiedvalue in this standard.

*Rules for rounding off numerical values ( revised).

IS : 1486 -1978

C-2.2 Pipette out 25 ml of the solution into a beaker, add 5 ml oftartaric acid solution and 4- ml of ammonia solution. (If the solutionturns deep blue, decolourize it by adding further tartaric acid.) Cooland add to the decolourized solution potassium h¥-Groxide solutiondropwise ( 2 to 4 rnl ) until a deep blue colour is o15fiined. Cool and addpotassium cyanide solution ( 4 to 6 ml ) until the solution becomes water­white or light yellow. Add four drops of thyrnolphthalein indicatorsolution and adjust the pH of the solution as follows:

If the colour of the solution after adding the indicator is deepblue or dirty green ( dependiug on the colour before adding theindicator ), add tartaric acid until the colour becomes light blue orlight yellow-green. When the solution is faint light blue (lightyellow-green), add ammonia solution till a deeper colour isobtained.

NOTE - The colour of the solution depends on the impurities present in thesolution.

C-2.3 Add 0'3 to 0'4 g of hydroxylamine hydrochloride to the solution,dissolve it and transfer the solution to a 250-ml separating funnel. Add25 ml of dithizone solution, shake and allow to settle•. Run the lowerlayer into a second separating funnel. Add 15 ml of dithizone and10 ml of carbon tetrachloride to the first funnel, shake, allow to settle andrun the lower layer into the second funnel. Then add 5 ml of ammoniasolution and 10 ml of carbon tetrachloride to the first funnel. Shake asbefore and examine the lower layer. If colourless or slightly green, runthe lower layer into the second funnel. If pink, add 10 ml of dithizonesolution, re-shake and run off the lower layer. Wash the aqueous layerwith another 10 ml of carbon tetrachloride solution and, if colourless,add it to the previous combined extracts. Discard the aqueous layer inthe first funnel.

C-2.4 Add the wash solution (see C-l.ll) to the combined extracts inthe separating funnel. Shake and allow to settle. The lower layershould have a .distinct pink colour and show no orange tint. Run thelower layer through a dry filter paper into a dry 100-ml volumetric flask.Extract the wash water with 10 ml of carbon tetrachloride and run itinto the 100 ml volumetric flask. Make up to the mark with carbontetrachloride.

C-2.5 Measure the intensity of the pink colour immediately on thespectrophotometer at 520 nm in l-cm cell using carbon tetrachloride asblank. The colour, finally measured. should be pink, as tendancy toan orange colour indicates the presence of oxidation products. Theextinction at 450 nm. should not be more than half of that at 520 nm,

APPENDIX D[Table 1, Item (vii) ]

DETERMINATION OF ARSENIC

D-O. GENERAL

D-O.l Arsenic is precipitated as the element from a solution of copperoxychloride in hydrochloric acid by sodium hypophosphite. Theprecipitated arsenic is dissolved in iodine solution and estimatedphotometrically after reduction of arsene molybdate to ' molybdenumblue '.

D-I. REAGENTS

D-I.1 Dilute Nitric Acid - 50 percent ( v/v ).

D-1.2 Concentrated Sulphuric Add

D-1.3 Concentrated Hydrochloric Acid

D-l.4 Sodiutll. Hypophosphite

D-l.5 Standard Iodine-Solution - 0'02 N,

D-l.6 Sodrum Bicarbonate Solution - normal solution.

D-I.7 Sulphuric Molybdate Reagent - Prepared by mixing equalvolumes of 13 N sulphuric acid and 6'9 percent (TTl/v) solution ofammonium molybdate.

D-I.8 Sodiutll. Metablsulphite Solution - 5 percent ( mlo ),

D-I.9 Stannous Chloride Solution - 0'2 percent (prepared bydiluting concentrated stannous chloride solution with water as required ).

D-2. PROCEDURE

0-2.1 Weigh accurately 2'5000 g of the material and dissolve it in -25 mlof dilute nitric acid, Add 6 to 8 ml of concentrated sulphuric acidwhen the effervescence, if any, has ceased. Carefully boil the solutionuntil it fumes, to remove organic matter. Cool, add 10 ml of water andrefume, taking care to avoid ' spitting'. Cool, and then dissolve the

10

IS : 1486 - 1978

salts by warming with 25 001 of water. Add to the solution 30 001 ofconcentrated hydrochloric acid and 4 to 6 g of sodium hypophosphite.Warm the solution on a hot-plate until the precipitation is complete andthen boil gently for 5 minutes to coagulate the precipitate.

D-2.2 Filter through a No. 4 sintered glass funnel. Wash the beakertwice with 15-001 portions of hot freshly-boiled water, pouring washingsthrough the funnel. Then wash the funnel four times, using 15001 ofhot water each time. Discard the nearly colourless filtrate andthoroughly rinse out the filter flask. Put the filter funnel in position andadd 20 001 of iodine solution to the precipitate. Draw the solution veryslowly through the filter until all the arsenic is dissolved. ( It is easy todetermine when the arsenic has been dissolved, since it is always in theform of a dark-brown or black finely-divided powder which shows upwell even in traces on the filter.) Again add 20 001 of iodine solutionand slowly draw through the filter. Wash the filter with 20 to 30 001 ofwater until an traces of iodine have been washed out. Transfer thissolution to a 100 001 volumetric flask and make up to the mark withdistilled water.

D-2.3 Transfer 5 001 of the above solution (01' less, arsenic contentis high) to a test tube with a mark at 9 001. Pipette out 1 001 of sodiumbicarbonate solution and 2 001 of sulphuric molybdate reagent into thetest tube. When the effervescence has ceased, add one to two drops ofsodium metabisulphite solution to decolourize the iodine. Make up thevolume to the 9 001 mark with water. Mix the solution well and "thenadd 1 001 of stannous chloride solution. Shake the test tube thoroughly.

D-2.4 After 5 minutes, measure the intensity of the blue colour developedon the spectrophotometer, preferably at 840 nm using a I-em cell anddistilled water as blank. If 840 nm cannot be attained by the spectro­photometer, a lower wavelength of 750 nm may be used.

D-3.CALCULATION

D-3.1 Calculate the amount of arsenic present in the material by plottingthe intensity of the colour so obtained on a standard curve previouslydrawn by using pure arsenic-free copper and arsenic trioxide ofanalytical reagent grade as standards in concentrations from 0 to 60 p.g.
