查询词典 oxidize

The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media. The dissolved weight of gold in 0.25 M thiourea solution with 0.05M Na〓SO〓 and 0.1M 〓 of pH 12. 5 by air at the temperature of 303K is 7. 8mg·cm〓 within 1hr.

在碱性硫脲溶金过程不起直接作用，而是通过S〓O〓来控制二硫甲脒有效形成的金在溶液中的混合电位；&混合电位&是影响碱性硫脲溶液溶金与否的决定性因素，在0.4V左右，有足够的推动力致使二硫甲脒氧化Au成Au〓，随后硫脲与Au〓络合形成稳定的络离子Au〓，从而使金快速溶解；温度为303K、pH为12.5时，在含0.05MNa〓SO〓、0.1M 〓及0.25M硫脲的溶液中，鼓入空气，金的溶解量在1hr内为7.8mg·cm〓；铜只有微量溶解，银、镍、铁则几乎不溶解。

Under the influence of the sunlight and with the help of its strong oxidization capacity, the photo-catalyst can oxidize nearly all the organic matters on the surface into H 2 O and the corresponding nontoxic inorganic materials. At the same time, under the combined actions of the characteristic nanometer structure of its surface, the hydroscopic properties of the complex additives and the light-induced amphiphilic properties (hydrophilicity and lipophilicity) of Ti02 itself the surface of the glass is made superhydrophilic, so that it becomes easily washable, anti-fog and not vulnerable to recontamination to keep the glass clean and transparent. And it also has such functions as sanitization, sterilization, foreign odor elimination and air refreshing.
