Cu-Zn coatings obtained by electrodeposition from acidic sulphate solutions containing sodium potassium tartrate and trisodium citrate as the complexing agents have been studied. 研究了以酒石酸钾钠(E337)、柠檬酸三钠作为络合剂的酸性硫酸盐溶液中的Cu-Zn合金镀层。
A method for analyzing Mo-Cu alloy is proposed in this paper. The sample is dissolved in mixed acids, Using sodium potassium tartrate to hide the matrix of Molybdenum, Copper and Nickel's content can be determined by electroanalysis and weight methods. 本方法采用硝酸&硫酸混合酸溶解试样,以酒石酸钾钠(E337)络合主体钼,用电解法和丁二酮肟重量法分别测定铜和镍的含量。
The results showed that the retarding effect of the retarders is citric acid > sodium citrate > tartaric acid > potassium sodium tartrate > sugar > phosphate. 缓凝剂对β半水膏的缓凝效果:柠檬酸>柠檬酸钠>酒石酸>酒石酸钾钠(E337)>蔗糖>磷酸盐。
Cobalt was deposited on spherical nickel hydroxide by electroless plating, using hydrazine or sodium hypophosphite as reductive agent and ammonia or potassium sodium tartrate as complexing agent, respectively. 采用水合联氨或次亚磷酸氢钠作还原剂,分别在酒石酸钾钠(E337)和氨的配合体系中镀覆球形氢氧化镍,对一定金属钴镀覆量下的产物进行了XRD和SEM分析与观测。
