Boron in nature's distribution mainly with all sorts of borates forms of ore exist, in the animal's each tissue and organ has distribution. At present in China, with rich resources of boron boron mine reserves total plan, ranked fifth. Boron USES is very extensive, is building materials, metallurgy, medicine, mechanical, electrical, chemical industry, light industry, nuclear industry, agriculture and defense departments such as sophisticated industries and important raw materials. Boron and utilization of the resources for the development of modern industry, has the more and more vital role.
Based on this method in HF medium, boron and F - formation BF4 - and then complexometric anions and mould purple formation ion in 630nm associating in things, determine its absorbency A. The concentration of boron in 30 ~ 150 g / 25ml apms within the scope of A linear relationship with A, which established A kind of determination method of boron.
希望采纳，绝对正确。。（我把一楼的答案逐词认证了，很累诶）
