ABSTRACT:
Specific toxicants are selectively removed from aqueous waste streams associated with the production of petroleum and petroleum products by contacting such aqueous waste streams with a non-ionic macroreticular polymeric resin having a low to intermediate surface polarity. The toxicants are a group of structurally-related organic molecules containing at least one carboxylic acid group and having a molecular weight in the range of about 200 to about 400. These molecules are toxic to certain indicator species of fish at concentrations of less than 10 parts per billion.
