摘　　要：根据GB/T11893-89水质总磷的测定钼锑抗分光光度法中使用过硫酸钾消解水样,日常所使用的压力锅因为温度控制的准确度会对样品测定结果产生影响,通常样品测定结果随消解温度的升高而升高,且水样中含非正磷酸盐越多,该变化趋势越明显。According to GB/Tl1893-89 water quality determination of total phosphorus molybdenum antimony spectrophotometry using potassium persulfate digestion of water samples, the daily use of the pressure cooker for accurate temperature control will affect the results of the determination of the samples, usually the determination results of samples increased with increasing temperature and digestion, samples containing non phosphate more, the change of the trend is more obvious.
