Glyphosate removal from contaminated water by natural clay, natural zeolite, commercial kaolin, bentonite, and sepiolite was compared. Natural clay showed high removal efficiency next to purified kaolin. The adsorption data for natural clay better fitted the Langmuir isotherm model and pseudo-second-order kinetic model. The adsorbent dose was found to be the most important process parameter while the pH did not exhibit any significant effect. An optimization study allowed achieving the highest removal efficiency and sorption capacity. The correlation coefficient R² of the regression model indicated that the observed results fitted well with the model prediction.

用于从污染水中去除草甘膦的高效低成本粘土基吸附剂

比较了天然粘土、天然沸石、商业高岭土、膨润土和海泡石从污染水中去除草甘膦的效果。天然粘土显示出仅次于纯化高岭土的高去除效率。天然黏土的吸附数据更符合朗缪尔等温线模型和准二级动力学模型。发现吸附剂剂量是最重要的工艺参数，而 pH 没有表现出任何显着影响。一项优化研究可以实现最高的去除效率和吸附容量。回归模型的相关系数R ²表明观测结果与模型预测吻合较好。
