Solving the problem of high lead contained in copper sulfate without any additional equipment(Invention patent authorized)

Source: Suzhou Canfuo Nanotechnology Co.,Ltd  Author: admin  Date: 2016-03-16

High lead has been a major problem restricting sulfate product quality, because lead is a highly toxic heavy metal elements, which can not be applied to feed but only inpesticides greatly reducing the product market while pesticides relies on season, and will therefore overstock in warehouse when in off season which will restrict the company operation.We have independently developed technology of copper sulfate to remove lead.This technology can mix reagent of clearing out lead with copper sulfate crystal,which have a good effect.When without the adding of this reagent,the products have 100-800ppm lead,and with this regent,the lead reduced to less than 10ppm.And because lead can dissolved in water thus won’t take new impurity to the product.Compare with the normal precipitation technology to eliminate lead,this method with advantage of easy operation,better effect and lower cost,will adding about 30-60 yuan per ton    copper sulfate. Solving this problem greatly broaden the application of copper sulfate , and enhance the market competitiveness of products.

The company has applied for patent protection for this technology, and the patent application number: 201110141206.2
