| 摘 要： | 采用过硫酸钾消解-钼锑抗分光光度法的方法测定污水处理厂剩余污泥中的总磷,通过实验确定最佳预处理方法、消解方法、过硫酸钾用量等分析条件。结果表明,方法线性良好,实际污泥样品的平行测定的RSD为0.5%～1.1%,加标回收率为97.0%～106%。

| Abstract: | The total phosphorus in surplus sludge of sewage treatment plant is determined by molybdenum antimony spectrophotometry with digestion of saturated potassium persulfate solution.The pretreatment,digestion and dosage of K_2S_2O_8 are optimized through experiment.The results show that the method has a sound linear,the RSD by parallel determination for the actual sludge sample is between 0.5% and 1.1% and the recoveries are between 97.0% and 106%. |
