Embodiment 1

[0027] The method for detection and resource utilization of simulated incineration products of phosphorus-based flame retardants in electronic waste provided in this example includes the following steps:

[0028] (S1) Analysis of phosphorus-based flame retardants in electronic waste: collect samples of electronic waste and analyze the composition of phosphorus-based flame retardants;

[0029] The addresses of the electronic waste samples were selected from Huadong Town, Huadu District, Guangzhou as the research area. It is characterized by a comprehensive industrial base dominated by light industry. Local light industries such as household appliances, consumer electronics, textiles and clothing, and toys are relatively developed.

[0030] Phosphorus-based flame retardants in e-waste samples were extracted by Soxhlet extraction, and the composition of phosphorus-based flame retardants was tested by GC-MS.

[0031] The specific process is as follows:

[0032] (1) Sample pretre...

Abstract

The invention discloses a method for detecting simulated incineration products of phosphorus-based flame retardants in electronic waste, comprising the following steps: (S1) analysis of phosphorus-based flame retardants in electronic waste; (S2) designing a simulated incinerator; (S3) electronic waste Simulated incineration of waste; (S4) analysis of incineration products; (S5) resource utilization of phosphorus components in electronic waste incineration products. This method simulates incineration in an incinerator and detects the type and content of phosphorus-containing components in the products before and after the simulated combustion of phosphorus-based flame retardants in electronic waste. A resource utilization method for phosphorus-containing components in products.

Description

technical field [0001] The invention belongs to the technical field of phosphorus-based flame retardants, and in particular relates to a detection and resource utilization method of simulated incineration products of phosphorus-based flame retardants in electronic waste. Background technique [0002] According to the data, in order to achieve the high flame retardant level of UL-94-V-0, it is generally necessary to add 20% to 28% flame retardant to the material internationally, and the domestic addition ratio is generally 26% to 30%. According to literature reports, at present, organophosphates are common pollutants in sewage, and it is generally believed that sewage treatment plants are the main source of organophosphates in surface water. According to the data of our general survey of sewage outlets entering the river, the total amount of sewage discharged by the electronics, home appliances, textiles, printing and dyeing industries in the Pearl River Delta region reached ...
