A new treatment method using a deep eutectic solvent embedded melamine sponge (DES-MS) was studied for the removal of organic pollutants from water and soil samples. Five organophosphorus pesticides (OPPs) consisting of azinphos-methyl (AZP), parathion-methyl (PRT), fenitrothion (FNT), diazinon (DIZ) and chlorpyrifos (CPF), and two dyes including acid blue 29 (AB29) and malachite green (MG) were used as the model pollutants. DESs were easily prepared from tetrabutylammonium bromide (TBABr) and various fatty acids. The synthesised DESs were loaded into the sponge before being utilized for the removal of the studied pollutants. After the removal, the residual OPPs or dyes in the supernatant was quantified by high performance liquid chromatography or derivative spectrophotometry, respectively. The proposed method was simple, rapid, environmentally friendly and effective with the removal efficiency higher than 70% for various samples. Moreover, the removal of various dyes was successfully achieved with the efficiency greater than 65% under the optimum condition.
一种使用深共晶溶剂嵌入三聚氰胺海绵（DES-MS）的新处理方法被用于从水样和土样中去除有机污染物。五种有机磷农药（OPPs），包括敌百虫（AZP）、对硫磷（PRT）、杀螟松（FNT）、敌敌畏（DIZ）和毒死蜱（CPF），以及两种染料，包括酸性蓝 29（AB29）和孔雀石绿（MG），被用作模型污染物。深共晶溶剂很容易由四丁基溴化铵（TBABr）和各种脂肪酸制备。合成的深共晶溶剂被加载到海绵中，然后用于去除研究中的污染物。去除后，通过高效液相色谱或导数分光光度法分别定量测定上清液中残留的 OPPs 或染料。该方法简单、快速、环保且有效，对各种样品的去除效率均高于 70%。此外，在最佳条件下，各种染料的去除效率大于 65%。
