Abstract: | By using chromogenic reaction of PAN-6S and Pb2+, plumbum in steel is determined. When the range is in pH=7.0- 10.0, PAN-6S and Pb2+ form a 1 : 1 red complex. The maximum absorption peak is at 543 nm and molar absorptivity is 1.12× 104. The plumbum in steel can be determined directly after adding masking agent. |
