Abstract

In this study, we have investigated how to reduce three emerging pollutants (atrazine, simazine and linuron) in water, through the use of advanced technologies such as powder activated carbon (PAC). Tests for contaminant reduction were conducted using ASTM D3860-98 in ultra-pure water. The concentrations were analyzed by HPLC equipment with an UV detector. The results obtained within 24 h at an initial concentration of 2,000 mg m-3 of the contaminant show that in PAC at 20,000 mg m-3 atrazine achieves a reduction of 65.4%, simazine achieves a reduction of 71.8% and linuron, a reduction of 70%.
