Abstract

The invention disclosed a synthetic method of the dithiocarbamic acid diethylene ethyl polymer and deals with the composing method of the dithiocarbamic acid polymer. The invention is the single stage process; the water, the sodium hydroxide, the diethylene tren, the carbon bisulfide and 1,2-dichloethane is mixed in turn to the polyreaction, so the adsorbent having the good ability of adsorbing the metallic ion. The invention has some merits of the easy means, the easy operation, the operator saving and the time saving, the water and organic solvent economy, the low cost of the producing, the wild acting condition, the safe produce, the energy saving, easy industrial production, the benefit of extending and applying. The production of the invention can be used for fathering the sullage containing the heavy-metal ion, so it can be applied to some trades such as the plate, the electron, the metallurgy, the petroleum processing and the pulp producing and is favourable to the environmental protection.

Description

1. Technical field

[0001] The invention belongs to the technical field of synthesis of heavy metal chelating agents, in particular to a synthesis method of dithiocarbamic acid polymers. 2. Background technology

[0002] In recent years, with the further improvement of my country's industrialization and urbanization, the continuous development of electroplating, metallurgy, petroleum refining, pulp production and other industries, the amount of wastewater containing heavy metal ions is also increasing. Excessive heavy metal ions in the water environment will affect the health and survival of humans and other organisms. When dealing with heavy metal ions, the traditional chemical precipitation method has disadvantages such as complex operation, heavy metal ions will be precipitated from the sludge again with the change of pH value, and cause secondary pollution. Therefore, it is necessary and urgent to explore and study effective methods and technologies for removing heavy me...
