This work examined the employment of different nanofiltration membranes for the separation of pesticide (i.e. atrazine and dimethoate) from aqueous solution. DK, NF270, NF200, and NF90 were tested for the pesticides retention performance under a stirred dead‐end filtration system. NF90 demonstrated the best pesticides retention performance with over 95% of retention for atrazine and approximately 80% for dimethoate. All the membranes consistently showed better retention of atrazine than dimethoate. Dissolving the pesticide in river or tap water amplified the overall pesticides retention performance, indicating that filtration in water treatment plants could render a superior pesticides retention performance. However, a lower flux was obtained for the filtration of tap and river water.
