Absorbtion of Sulfamethoxazole an Organic

Background
The summer pre freshmen engineering program (PREP) molded my brain and in my 4th year the focus of the program was water management and treatment.
PREP took the 4th year students on a tour to San Antonio Water Systems (SAWS) we saw the water management and treatment systems.
Motivation
The research objective was to remove pharmaceuticals from waste water and storm water. The removal of pharmaceuticals would
protect fish populations and prevent undetermined long term health effects on humans
Objective
Need for a low-cost sorbent
Wastewater emerging contaminants Pharmaceuticals and
personal care products Indirect water reuse
Improve drinking water source quality
Remove natural organic matter (NOM) DBP precursors
Increasing loads of synthetic organics, such as pesticides in developing countries
So there is a need for removal but there is still yet a demand to remove these compounds Sulfamethoxazole was used in the study
It is used to treat urinary tract infections Removal of compounds by adsorption to a
solid material (adsorbent) Bio Chars can become to answer to a problem
that we know about, but refuse to look at.

PAC was the best performing char used but there is still data proving other options are available
The experiment has room for improvement and expansion
Future test many look at the other chars not searched here
Future test may have a mixture of chars The field of biochar had the potential to solve the
growing issue with pharmaceuticals in the water
