Solid chelating agent for living landfill standard and preparation method thereof
The invention provides a solid chelating agent for a living landfill standard and a preparation method thereof, and relates to the technical field of chelating agents. The solid chelating agent for the living landfill standard is prepared from the following raw materials in parts by weight: 2-4 parts of solid magnesium oxide, 70-90 parts of solid potassium dimethyl dithiophosphate, 15-20 parts of solid dipotassium hydrogen phosphate, 2-4 parts of borax, 10-20 parts of cellulose, 20-40 parts of amine substances, 6-8 parts of lime powder, 2-4 parts of diatomite, 3-5 parts of attapulgite, 2-3 parts of humic acid, 1-2 parts of an active agent and 1-2 parts of a dispersing agent. The solid chelating agent can quickly react, can be stable for a long time, can reach the standard for a long time, can be combined with metal ions, can improve the structure of landfill soil, has the effects of exchange, adsorption, complexation, chelation and the like with the metal ions, can be used as polyelectrolyte in a dispersion system, has the effects of condensation, peptization, dispersion and the like, meanwhile, the solid chelating agent has a certain number of free radicals on molecules, and has physiological activity.
本发明提供一种用于生活填埋标准的固体螯合剂及其制备方法，涉及螯合剂技术领域。该用于生活填埋标准的固体螯合剂包括以下重量份的原料组成：固体氧化镁2‑4份、固体福美钾70‑90份、固体磷酸氢二钾15‑20份、硼砂2‑4份、纤维素10‑20份、胺类物质20‑40份、石灰粉6‑8份、硅藻土2‑4份、凹凸棒土3‑5份、腐殖酸2‑3份、活性剂1‑2份、分散剂1‑2份。本发明，固体螯合剂既能迅速反应，又能长期稳定，且能长期达标，能与金属离子结合，并能改良填埋土壤结构，与金属离子有交换、吸附、络合、螯合等作用，能在分散体系中作为聚电解质、有凝聚、胶溶、分散等作用，同时，固体螯合剂在分子上还有一定数量的自由基，具有生理活性。
