A recent study on adsorption of metolachlor on activated carbons carried out by Gomis-Berenguer has reported higher adsorption capacity for pure -metolachlor compared with the adsorption capacity for the racemic mixture of this pesticide. The authors claim that the adsorption is enantioselective, with the activated carbon being more efficient for the adsorption of the enantiomer compared with the enantiomer. In this comment, we question this explanation (since the non-chiral surface of an activated carbon would never be selective towards one enantiomer instead of the other) and we offer some possible answers supported by theoretical calculations.
戈米斯 - 贝伦格尔最近进行的一项关于甲草胺在活性炭上吸附的研究报告称,与该农药的外消旋混合物的吸附容量相比,纯甲草胺的吸附容量更高。作者声称吸附具有对映选择性,活性炭对(一种对映体)的吸附比对映体更有效。在本评论中,我们对这种解释提出质疑(因为活性炭的非手性表面永远不会对一种对映体比对另一种对映体更具选择性),并且我们提供了一些有理论计算支持的可能答案。
