铝的比色测定法很多,最常用的方法是用金黄色素三羧酸的铵盐(铝试剂)为显色剂。近三十年来,各国化学家在这方面已经进行过大量工作,但是存在的问题还很多,所以最近仍陆续有论文发表。此法的主要问题是影响颜色深度的因素太多:例如显色时溶液的 PH、温度、加热的时间、显色后放置的时间、比色时的温度、铝试剂的来源和品质
Aluminum colorimetric determination of many, the most common method is to use the golden yellow pigment tricarboxylic acid ammonium salt (aluminum reagent) as the color reagent. In the past three decades, a great deal of work has been done by chemists in various countries in this field, but many problems still exist. Therefore, papers have been published recently. The main problem with this method is that there are too many factors affecting the color depth: for example, pH of the solution during color development, temperature, time of heating, time after color development, temperature at colorimetric, source and quality of aluminum reagent
