摘要
分析过硫酸钾纯度对碱性过硫酸钾消解紫外分光光度法测定水质总氮的影响,提出用重结晶法提纯过硫酸钾可以满足总氮测定的质量控制要求。
Analyzed the influence of potassium persulfate purity to TN detection by UV spectrophotometry digested by Alkaline potassium persulfate. Potassium persulfate purified by recrystallization method can meet the quality control requirements of TN detection.
