| Abstract: | This paper described a new method for the trace determination of fenpropathrin, cyhalothrin and deltamethrin using multiwalledcarbon nanotubes (MWCNTs) cartridge. Important parameters, such as the sample pH, eluent and its volume, sample flow rate andsample volume were investigated in detail. The linear ranges, the detection limits, and precisions (R.S.D.) were in the range of 0.1-40 μg L-1 1.3-4.3 ng L-1 and 2.3-2.8%, respectively. The performance of the proposed method was validated with real watersamples, and the spiked recoveries were in the range of 91.7-117.8%, respectively. The experimental results demonstrated that theproposed method was an excellent alternative for the routine analysis of such pollutants in environmental samples. |
