摘要
通过大量试验 ,对氯化亚锡还原光度法测定总磷过程中如何延长氯化亚锡、磷酸二氢钾试剂的使用保存期、提高显色的稳定度、降低空白值 。
On the basis of plentiful experiments, this paper suggests doable improvement method in the progress of determination total phosphorus by deacidized tin chloride photometric approach that how to prolong using storage life of SnCl 2 and KH 2PO 4, advance colouring stability and debase blank value.
