Adsorption—Photometric and Test Determination of Copper Using Silica Gel Sequentially Modified with Polyhexamethylene Guanidine and Bathocuproinedisulphonic Acid
The interface interaction of Cu(I) with 2,9-dimethyl-4, 7-diphenyl-1,10-phenanthrolinedisulphonic acid immobilized onto silica modified with polyhexamethylene guanidine was studied. The high affinity of metal ion to the modified silica surface was found to be due to the presence of a complex, which...
