| Abstract: | The total phosphorus in surplus sludge of urban sewage treatment plant was determined by molybdenum antimony spectrophotometry with digestion of saturated potassium persulfate solution.By optimizing pretreatment,digestion,dosage of K2S2O8 and quality of sludge sample,good linearity was obtained.The RSD of parallel sludge samples was≤1.0%.Spiked recoveries were between 98.0% and 104%. |
