| Abstract: | For the purpos e of determining total phosphorus in wastewater by ICP-OES,the law of spectrum sensitivity change has been obtained by determining the spectrum intensity under different conditions,such as different RF power,observation height,carrier gas flow and injection volume.Samples are determined after optimizing the parameters of ICP.The results show that the detection limit is 0.05 mg/L,relative deviation of QC sample 1.21%,RSD 0.96%(n=6),and sample recovery rate about 98.4%.The dosage of reagent by ... |
