The present study assessed the removal of fenamiphos, imidacloprid, and oxamyl pesticides from water using algal biomass. Several factors, such as algal biomass concentration, incubation time, and pesticide concentration, were studied for their impact on pesticide removal. Analysis and quantification of pesticides by rapid HPLC have been developed and validated. The optimum conditions were obtained at 15 min, 50 mg/L of pesticide concentration, and 4,500 mg/L of the algal biomass with 92.24% and 90.43% removal for fenamiphos and imidacloprid, respectively. While optimum parameters of 10 min incubation, 250 mg/L of pesticide concentration, and 2,750 mg/L of the algal biomass exhibited 67.34% removal for oxamyl. , marine microalgae, successively removed different concentrations of the tested pesticides from water, and the algal biomass showed a potential reduction of pesticides in polluted water samples.
本研究评估了利用藻类生物量从水中去除fenamiphos、imidacloprid 和 oxamyl 农药。研究了藻类生物量浓度、孵育时间和农药浓度等几个因素对农药去除的影响。开发并验证了通过快速 HPLC 分析和定量农药的方法。在 15 分钟、50 毫克/升的农药浓度和 4500 毫克/升的藻类生物量条件下，fenamiphos 和 imidacloprid 的去除率分别达到 92.24%和 90.43%。而在 10 分钟孵育、250 毫克/升的农药浓度和 2750 毫克/升的藻类生物量的最佳参数下，oxamyl 的去除率为 67.34%。研究表明，海洋微藻能够从水中去除不同浓度的测试农药，藻类生物量显示出在污染水样中减少农药的潜力。
