摘要:利用PAN-6S与Pb2+的显色反应测定钢铁中铅的含量.在pH=7.0~10.0范围内PAN-6S与Pb2+形成物质的量比为1∶1的红色配合物,其最大吸收峰在543 nm处,摩尔吸光系数为1.12×104,加入掩蔽剂后可直接测定钢铁中铅的含量.
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.
