摘　　要：本文基于莫尔法建立了一种现场快速检测肥料中氯离子含量等级的方法,通过与国标佛尔哈德法的对比,该方法可以准确快速地检测未标含氯(即不含氯)、含氯(低氯)、含氯(中氯)的肥料产品,该方法操作简便,检测效率高,使用设备简单便携,适用于各种检测环境,可以作为国标佛尔哈德法的补充,用于肥料产品氯离子含量的初步判定。该方法对于提升市场监管效率,肥料企业产品质量提升,保护肥料使用者利益有着一定的现实意义。This paper established a method to quickly detect the content grade of chloride ion in fertilizer on the spot based on the Mohr method.Compared with the national standard Folhard method,this method can accurately and quickly detect fertilizer products that are not labeled with chlorine(without chlorine),containing chlorine(low chlorine),and containing chlorine(medium chlorine).This method is simple to operate,high detection efficiency,simple and portable to use,and suitable for various detection environments,It can be used as a supplement to the national standard Folhard method for the preliminary determination of chloride ion content in fertilizer products.This method has certain practical significance for improving the efficiency of market supervision,improving the product quality of fertilizer producer,and protecting the interests of fertilizer users.
