砷

When cathodic potential is negative enough,arsenic acid, arsenious acid and element arsenic co-discharge and AsH3 is evolved.

在铜电解液净化工序中，砷酸优先于亚砷酸析出砷化氢，当阴极电势足够负时，三者共同放电析出砷化氢。

Oxygen that is evoluted in the anode and arsenic acid will have oxidation-reduction to produce arsenic acid. It can evolute a great amount of hydrog...

在铜含量较低时阴极析出大量氢气，阳极析出氧气，极大地浪费了电能；在析出氢气的同时逸出砷化氢，砷酸、亚砷酸在阴极直接发生还原反应也产生砷化氢气体，从而严重地污染了环境。

Oxidation of arsenic in solution to arsenic, and reduction of arsenic to arsenic have been investigated as part of the overall chemistry relating to hydrometallurgy.

3价砷的氧化物在溶液中变成＋5价砷，并且＋5价砷的减少变成＋3价砷也已经作为所有有关湿法冶金法的化学作用的一部分被研究。

Arsenic-alkali residue, being dangerous to the environment, is a solid waste of antimony production by pyrometallurgy. So it's of very importance to treat and utilize arsenic-alkali residue comprehensively, which can both eliminate the environmental pollution and recycle the resource of arsenic and antimony, with high social and economic benefits.

砷碱渣是火法炼锑加碱除砷过程产生的固体废物，砷碱渣的综合利用不但能消除废渣对环境的危害，而且可回收其中的有价金属砷和锑，因而具有显著社会效益和经济效益。

The calibration curves for arsanilic,nitarsone and roxarsone were linear over the concentration ranges of 0.5-50 mg/L and their correlation

阿散酸、硝苯砷酸和洛克沙砷的定量线性范围为0.5~50 mg/L，线性相关系数均大于0.999；检出限阿散酸为0.095mg/kg、硝苯砷酸为0.18 mg/kg、洛克沙砷为0.19 mg/kg；保留时间的相对标准偏差不大于0.51%。

Traditionally, it was divided into acute and chronic arseniasis, which were decided mainly by exposing dose and time from exposure to attack.

传统砷中毒的概念分急性砷中毒和慢性砷中毒，它们主要是由于机体单位时间接触砷的量和从接触到发病的时间长短来决定。

The experiments included both small and extended test. Because the Arsenic in secondary zinc oxide exists mainly in the form of arsenous oxide, which is volatile, the roasting method of adding reductant carbon to secondary zinc oxide is used to remove Arsenic.

本研究实验包括小型实验和扩大实验，由于次氧化锌中砷主要以三氧化二砷形态存在，因此可以通过三氧化二砷易挥发特性，采用在次氧化锌中加入炭还原剂的焙烧方法脱砷。

Dose-dependent toxic effects in primary cultured astroglia could be induced by exposed to iAsⅢ or iAsⅤ within the concentrations of 25～100 μmol/L or 100～500 μmol/L, respectively.

接触最少25 μmol/L的3价无机砷或100 μmol/L的5价无机砷对星型胶质细胞可产生明显的毒性损伤作用。3价无机砷的毒性明显大于5价无机砷。

Dose-dependent toxic effects in primary cultured astroglia could be induced by exposed to iAsi or iAsv within the concentrations of 25～100μmol/L or 100～500 μmol/L, respectively.

接触最少25μmol／L的3价无机砷或100μmol／L的5价无机砷对星型胶质细胞可产生明显的毒性损伤作用。3价无机砷的毒性明显大于5价无机砷。

Meanwhile, the standard experiment on addition of small molecular organic arsenics revealed that the small molecular organic arsenics such as cacodylic acid, disodium methylarsonate were detected to be inorganic arsenic by the two detection methods with high recovery efficiency.

同时，试验中用小分子有机砷进行加标试验，结果表明：二甲基胂酸、甲基胂酸二钠等小分子有机砷对两种测定方法的影响很大，会把小分子有机砷作为无机砷检测出来，且检出回收率很高。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
