Embodiment 2

[0033] The method according to Embodiment 1 of the present invention uses nanometer zero-valent iron to degrade bisphenol A, comprising the following steps:

[0034] (1) Preparation of nanometer zero-valent iron (nFe 0 ); The preparation process of the nanometer zero-valent iron is:

[0035] (1-1) First boil the ultrapure water for 20 minutes, then pass high-purity nitrogen into the ultrapure water for 30 minutes to remove the oxygen and cool it to obtain anaerobic water, and weigh 0.01mol of FeSO 4 ·7H 2 O and 0.02 mol of NaBH 4 respectively dissolved in 50ml of anaerobic water to obtain FeSO 4 solution and NaBH 4 solution;

[0036] (1-2) The configured FeSO 4 ·7H 2 The O solution was placed in a three-necked flask equipped with mechanical stirring, and NaBH was slowly and evenly added dropwise to it with a rubber dropper. 4 solution, mechanical stirring during the dropping process, Fe 2+ with BH 4 - The ions react as follows:

[0037] Fe 2+ +2BH 4 - +6H 2 O→n...

Abstract

The invention discloses a method for degrading bisphenol A by activating sodium percarbonate with nanometer zero-valent iron, and catalytically activating sodium percarbonate to degrade bisphenol A after preparing nanometer zero-valent iron. The reaction conditions are mild and easy to operate; nanometer zero-valent iron is used as the reaction system The catalyst activates the oxidant sodium percarbonate to generate OH and O 2 ·‑ Free radicals degrade bisphenol A, the degradation process is simple, and the degradation efficiency is high; the catalyst can be recycled and reused, and the oxidant is convenient for storage and transportation, with high activity and stability.

Description

technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a method for degrading bisphenol A by activating sodium percarbonate with nanometer zero-valent iron. Background technique [0002] With the rapid development of my country's industry, a large amount of industrial production wastewater containing various pollutants has been discharged, which has caused increasingly serious impacts on the environment. Bisphenol A (BPA), as one of the most produced chemical raw materials in the world, is also a representative environmental endocrine disruptor. Even when its concentration is very low, it can still cause adverse effects on the normal growth, reproduction and endocrine of biological organisms. In the related art, the traditional Fenton reagent is used to process bisphenol A, and there is a large amount of Fe 2+ It is difficult to separate, recycle and reuse, a large amount of iron sludge is produced after th...
