Today, a variety of pesticides are used to combat plant pests worldwide. The entry of these resistant pollutants into water resources can have devastating effects on human health and the environment; hence their removal from the environment is a vital task.

In this research, the GO/ZIF-8 composite was synthesized by the solvothermal method and used for the removal of diazinon (DIZ) and chlorpyrifos (CLP) pesticides from the aqueous solution. To determine the simultaneous concentration of DIZ and CLP in aqueous solutions after the removal with GO/ZIF-8 nanoparticles, the partial least squares method (PLS) was used. The values of the evaluation parameters such as R² (0.995, 0.998,), Recovery percentage (101.42, 99.90 %), and Root Mean Square Error of Prediction (0.204, 0.201) for both CLP and DIZ obtained by the PLS method were satisfying. Also, to optimize the factors affecting the adsorption process such as pH, adsorbent dose (mg), and contact time (min), the response surface methodology (RSM) was used. The optimal conditions for each variable were achieved by the desirability function approach (DFA). The results showed that the highest removal efficiencies (%) under the conditions; pH=7, adsorbent dosage 24 mg, and contact time 24 min for chlorpyrifos and diazinon were obtained 83% and 73%, respectively.

今天，世界范围内使用多种杀虫剂来对抗植物害虫。这些具有抗性的污染物进入水资源会对人类健康和环境产生破坏性影响；因此，将它们从环境中移除是一项至关重要的任务。

在本研究中，GO/ZIF-8 复合物通过溶剂热法合成，用于去除水溶液中的二嗪农 (DIZ) 和毒死蜱 (CLP) 农药。为了测定用 GO/ZIF-8 纳米颗粒去除后水溶液中 DIZ 和 CLP 的同时浓度，使用偏最小二乘法 (PLS)。R ²等评价参数的值通过PLS方法获得的CLP和DIZ的回收率（0.995，0.998，），回收率（101.42，99.90％）和均方根预测误差（0.204，0.201）均令人满意。此外，为了优化影响吸附过程的因素，如 pH、吸附剂剂量 (mg) 和接触时间 (min)，使用响应面方法 (RSM)。每个变量的最佳条件是通过合意性函数方法 (DFA) 实现的。结果表明，该条件下的去除效率（%）最高；pH=7，吸附剂用量24mg，毒死蜱和二嗪农的接触时间分别为83%和73%，接触时间为24分钟。
