含有微量锌、锰的磷矿制造肥料,在一定条件下,可以提高作物的产量和质量,防止植物病害等。因此,调查磷矿中微量锌、锰的含量有着重要的意义。原子吸收分光光度法连续测定锌、锰等已有不少报导。但是,磷矿中锌、锰的连续测定,由于钙、镁、硅、铁等的干扰和火焰背景影响较大而未见报导。 Fertilizers containing trace amounts of zinc and manganese can increase the yield and quality of crops and prevent plant diseases under certain conditions. Therefore, the investigation of trace amounts of zinc and manganese in phosphate rock is of great significance. Atomic Absorption Spectrophotometry continuous determination of zinc, manganese and many other reports. However, the continuous determination of zinc and manganese in phosphate rock has not been reported because of the interference of calcium, magnesium, silicon, iron and the flame background.
