测定磷矿中的磷,多用部颁标准法——钼酸喹啉重量法或滴定法,准确度高,重现性好,但是操作过程长,使用试剂多,喹啉试剂污染环境。为克服不足,已有文献介绍,本文借鉴文献,对磷矿中全磷的测定,用离子交换法进行试验,得到准确度高,重现性好,操作简便,节省时间,试剂,不污染环境的效果。故此法可作为内部快速测定磷矿全磷含量之用。
Determination of phosphorus in phosphate rock, and more ministerial standard method - quinoline molybdenum gravimetric method or titration, high accuracy, reproducibility, but the long operation, the use of reagents, quinoline reagent pollution of the environment. In order to overcome the deficiency, the literature has been introduced. This paper draws on the literature, the determination of total phosphorus in phosphate rock, using ion exchange method to test, get high accuracy, good reproducibility, easy operation, time saving, reagent, Effect. Therefore, this method can be used as an internal rapid determination of phosphate rock phosphate use.
