Grined zincblende are produced at Budo Mine (Located in Niigata Pref.) was treated in solution reactions upon various pH solutions, and the changes of grain surface was analized in accordance with pH change, wetness, and electropholysis.
1. Adsorption of H⁺ and OH^- ion to zincblende are is propotional to the concentration of solution, and are grain itself is changed positive or negative respectivly.
2. Adsorption quantity formula : Mz=10^{2.82 | PH-7 |}
(Adsorption quantity=Mz in unit of 10^-7mol, pH=pH of original solution)
3. Adsorption quantity was maximum at the vicinity of 1535°C test condition.
4. Fahrenwald's theory is not correct for the adsorption action at 7 of pH, but it is seemed to be correct by some other are grain experiments.
5. Adsorption quantities is proportional to electrophysis and degree of wetness.
6. Electrophyolysis velocity formula (at 30 volt D. C) : Sz=PH-4/364
(Sz=Electrophyolysis velocity, pH=pH of original solution)
