A procedure has been developed for the determination of iron(III) dimethyldithiocarbamate by converting it into the iron(II)-bathophenanthroline complex, which is then dissolved in acetone-water (1:1), and the absorbance is measured at 534 nm against a reagent blank. Beer's law is obeyed over the concentration range 0.5-20 microg x mL(-1) in the final solution. The method is sensitive and highly selective and is used for the direct determination of ferbam in a commercial sample and in mixtures with various dithiocarbamates (ziram, zineb, maneb, etc.) and from wheat grains.
已开发出一种测定二甲基二硫代氨基甲酸铁（III）的方法，即将其转化为铁（II）-邻二氮菲配合物，然后将其溶解在丙酮-水（1:1）中，并以试剂空白为参比在534nm处测量吸光度。在最终溶液中，浓度范围为0.5-20μg·mL⁻¹时符合比尔定律。该方法灵敏且选择性高，用于直接测定市售样品以及与各种二硫代氨基甲酸盐（福美双、代森锌、代森锰等）的混合物中的福美铁，也用于测定小麦籽粒中的福美铁。
