The effects of AgNO3 concentration,the amount of graphite powders and cathode efficiency on silver content and electroplating effect of the silver electroplating graphite powders were analyzed in detail.
研究了镀液中硝酸银浓度、石墨粉加入量和阴极电流密度等工艺条件对镀银石墨粉含银量和电镀效果的影响。
Then the concentrate with inclusion of perchlorates was decomposed at the high temperature and the perchlorates content were determined by the argentometric method.
〔方法〕烟火药剂洗去有机粘合剂后,用热水溶解使高氯酸盐从烟火药剂中还原分离,高温使高氯酸盐分解成氯化物,然后用银量法测定氯,进而得到高氯酸盐含量。
Results:The argentometric method showed an average recovery rate of 99.
方法:采用银量法、紫外分光光度法和高效液相色谱法分别对泰妥拉唑进行含量测定。
