意的结果,产品透光度达到100％,和蒸馏水一样清。此法工艺设备简单,效率较高、操作容易、生产成本低,适于一般工厂和中学校办厂推广采用。一、原理与方法纯盐酸为无色透明浓体,工业盐酸则因有杂质(如铁)而带有黄绿色和其他色泽。Fe~(3+)离子在浓盐酸中是以络合阴离子的形式存在的:
As a result, the transparency of the product reached 100%, just as clear as distilled water. This method process equipment is simple, high efficiency, easy operation, low production costs, suitable for general factory and secondary school set up factories to promote the use of. First, the principle and method Pure hydrochloric acid is colorless and transparent concentration, industrial hydrochloric acid due to impurities (such as iron) with yellow-green and other colors. Fe 3+ ions exist as concentrated anions in concentrated hydrochloric acid:
