硼在自然界的分布主要以各种硼酸盐形式的矿存在,在动物的各个组织和器官中也有分布。我国硼资源丰富,目前以硼矿总储量计,居世界第五。硼的用途十分广泛,是建材、冶金、医药、机械、电器、化工、轻工、核工业、农业以及国防尖端工业等部门的重要原料。硼资源的开发、利用,对于现代工业的发展,具有越来越重要的作用。
该方法基于在HF介质中,硼与F-形成络合阴离子BF4-,然后与结晶紫形成离子缔合物,在630nm处测定其吸光度A。硼的浓度在30~150µg/25ml范围内与A成线性关系,据此建立了一种测定硼的方法。 展开

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)
