| Abstract: | Studies of the influence of KCl on Ag sol, Ag sol-pyridine and Ag sol-bensoic acid system are reported. Experimental results reveal that the influence of Cl~- on the above systems is obviously different. It is found that the absorption spectrum of Ag sol is similar to that of Ag sol-benzoic acid, but is quite different to Ag sol-pyridine after adding KCl into these three systems respectively. |
