我們的工業对銅的純度提出了重大的要求,特別是關於雜質砷与銻惡化陰極銅的質量的問題。因此本文中着重地研究二者在電解精煉銅時的行為。 雖然关於這個問題的著作很多(如巴依玛科夫)所指出的:到目前為止,還不清楚,()極如何為所謂雜質染污,在工廠的正常工作條件下,As與Sb能否和銅一起電解沉積於陰極上;关於含As與Sb的沉積物由電解液析出的知识,與‘漂浮’泥渣在電解槽表面上形成的條件的知识也不够,因此而惡化了陰極銅的質量:關於砷與銻自陽極溶解時其原子價的知識,和其以後的變化的知識相矛盾。所以,像含As与Sb的沉積物以何種速度由電解液析出,我們知道的非常少,大概沉積物的形成与它們的原子價有关。在此文中,我們力求闡明:(1)As与Sb能否与銅一起電解沉積於陰極上;(2)電解液中的As与Sb的原子價為甚麼改變和如何改變?(3)含As与Sb的沉積物,包括‘漂浮’泥渣在內,在電解質中形成的條件是怎样的?
Our industry places significant demands on the purity of copper, especially with regard to the quality of impurities that deteriorate the quality of copper cathodes. Therefore, this article focuses on the behavior of the two in the electrolytic refining of copper. Although many of the works on this issue (eg, Bayhimekov) point out: So far it is unclear how () extremely contaminated so-called impurities, under normal operating conditions in factories, can As and Sb And the copper is electrolytically deposited with the cathode on the cathodes. Knowledge of the precipitation of the deposits containing As and Sb from the electrolytic solution is not sufficient as the knowledge of the conditions for the formation of the ’floating’ sludge on the surface of the cell, thereby deteriorating the quality of the cathode copper : Knowledge of the valences of arsenic and antimony dissolved from the anodes contradicts their later knowledge of change. So, as the speed of sediment containing As and Sb precipitated from the electrolyte, we know very little about the formation of sediments related to their valences. In this article, we seek to clarify: (1) Whether As and Sb can be electrodeposited together with copper on the cathode; (2) Why the atomic valences of As and Sb in the electrolyte change and how they change? (3) What is the formation of Sb in the electrolyte, including the “floating” sludge?
