工业浓盐酸或氯化副产盐酸，由于设备腐蚀或水质的原因而带有一定的黄色，严重影响其应用范围。盐酸的黄色主要是铁引起的。苏青牌SQD-74可以有效去除浓盐酸中的铁，经处理以后的盐酸无色透明，大大提高了盐酸的品质。而且使用方便，寿命长，处理成本很低。
Industrial grade concentrated hydrochloric acid and the by-product hydrochloric acid of chlorination are usually light yellow color, because of the equipment erosion and/or bad water quality used. This color largely limits the acid’s applications. The color, however, is caused by iron. Suqing SQD-74 can effectively remove iron from the concentrated hydrochloric acid. The treated acid is water clear and its quality is largely increased. The resin is very convenient to be used, has a long life time. This treatment is very cost-effective.

树脂再生方法(Regeneration Method)
SQD-74可以有效去除浓盐酸中的铁。树脂失效后用除盐水淋洗至出水无黄色可以有效再生并重复使用。
SQD-74 can effectively remove iron from the concentrated hydrochloric acid. After the resin is exhausted, it can be regenerated easily by rinsing the resin with Di water until no yellow color is released. Now the resin is ready for re-use.
