摘要
采用过硫酸铵法测定水中总磷,通过大量试验探寻其标准样品的工作曲线,并对其稳定性、精密度、回收率以及试验样品取样方式等进行对比分析,结果表明:此法线性好,稳定性好,分析时间短,操作简便,便于掌握,能够满足企业实际生产需要。
The ammonium persulphate method is used to determine total phosphorus in water. A large number of tests are made to explore work curve of the standard samples. The stability, precision, recovery of the method and sampling method of test samples are analyzed.The results show that this method has good linearity, good stability, short analysis time, easy to operate, easy to master and can meet the needs of actual production.
