| Abstract: | Removal of trace triazophos from drinking water by nanofiltration membranes techniques was investigated.Experiments were done with two types of nanofiltration membranes including NF200 and NF90.Results indicated that the trace triazophos could be removed efficiently by NF200 and NF90,with rejection of triazophos about 90% for NF200 and rejection of triazophos above 97% for NF90.Effects of various operating conditions such as operating pressure,feed concentration,pH and ionic strength were also studied.It wa... |
