Transformation of various oxygen species adsorbed on electrolytic silver surface pretreated by pure oxygen at 423～973 K under ambient pressure was observed for the first time by in situ confocal microprobe Raman spectroscopy.

for acetaldehyde production by ethyl alcohol oxidation process,electrolytic silver catalyst can efficiently reduce side reaction and energy consumption.

The factors of effect on the techniques of the electrolytic silver were analyzed.

Sequential determination of free nitric acid,copper and silver in silver electrolyte;

Behavior of impurities in silver electrolyte during electrolysis are introduced.

Through controlling the technological conditions of preparing of silver anode,silver electrolysis, silver casting strictly, we can obtain the high quality electrolytic silver which has beautiful appearance,pure color.

By improvement of absorption method of electrolyte and conjunction method of cathode in silver electrolysis ,the effective production time is increased ,the problems existed before are overcome, the electric consumption is decreased and the electric efficiency is increased at the same time.

The behavior and control of major impurities in silver electrolysis process are investigated in the paper.

Experimental study on a new type technology of mechanized electrolytical refinement of silver;

Objective To investigate the effect of head down bed rest(HDBR) or electrolytic silver ion on intestinal bifidobacteria in men and mice.
