几种氯化物对胶体钯活化液稳定性及其催化活性的影响

Effect of Some Chloride on the Stability and Catalytic Activity of Colloidal Pd Activation Solution

胶体钯活化液的稳定性主要取决于Sn^(2+)、H^+和CΓ的浓度.NaCl、NH_4CI或KCl代替盐酸能增强活化液的稳定性,且可保持其催化活性.

The stability of colloidal Pd activation solution mainly depends on the concentration of Sn^(2+), H^+ and Cl^-. Replacing hydrochloric acid by sodium chloride, ammonium chloride or potassium chloride can enhance the stability of Pd activation solution and maintain its catalytic activity
