Embodiment 1

[0035] A method for preparing a composition for removing heavy metal Cd in water, comprising the steps of:

[0036] The first step: the active ingredients of the aqueous fatty acid ethyl ester suspoemulsion are saturated fatty acids and unsaturated fatty acids, and the concentration of the active ingredients in the aqueous fatty acid ethyl ester suspoemulsion is 0.1%-99.9%. Purchased by South Africa (Pty) Ltd;

[0037] Step 2: Measure the water-based fatty acid ethyl ester suspoemulsion and the silicon-rich solution at a ratio of 1:100 to 100:1 by volume, and put it into a reaction kettle with a stirrer. At room temperature, press 50--100r / min Stir for 30min-14 days to prepare the composition for removing heavy metal Cd in the water body. The silicon-rich solution is a mixed solution of one or two solutions in potassium silicate solution and sodium silicate solution. The concentration of the silicon-rich solution is 5- 500000mg Si / L.

[0038] The application of the compositi...

Embodiment 2

[0056] A method for preparing a composition for removing heavy metal Cd in water, comprising the steps of:

[0057] The first step: measure the water-based fatty acid ethyl ester suspoemulsion and the silicon-rich solution at a volume ratio of 1:100 to 100:1. The active ingredients of the water-based fatty acid ethyl ester suspoemulsion are saturated fatty acids and unsaturated fatty acids. The concentration of the active ingredient in the fatty acid ethyl ester suspoemulsion is 0.1%-99.9%. The Si-rich solution is a potassium silicate solution and a sodium silicate solution or a mixed solution of the two solutions. The concentration of the Si-rich solution is 5-500000mgSi / L;

[0058] The second step: put the measured water-based fatty acid ethyl ester suspoemulsion and silicon-rich solution into a reaction kettle with a stirrer, and stir at 50--100r / min for 30min-14 days at room temperature to prepare the heavy metal removal in water Composition of Cd.

Embodiment 3

[0074] The third experiment was carried out at the Institute of Basic Biology of the Russian Academy of Sciences. The main purpose of this test is to prove that it is feasible to remove cadmium from industrial wastewater by using the composition for removing heavy metal Cd in water. This experiment was carried out with sodium silicate solution A (China) and liquid glass (Ivdis Ltd., Russia). The wastewater was taken from the Kursk Battery Enterprise (Kursk, Russia). The chemical composition of the wastewater is shown in Table 4. The characteristics of the silicon-rich solution are shown in Table 1. Two concentrations of FA were used: 50 g / L and 200 g / L.

[0075] According to the volume ratio of 10:1, FA was mixed with the silicon-rich solution, and the composition mixture for removing heavy metal Cd in water was prepared after 1 day.

[0076] The composition mixture for removing heavy metal Cd in water is added to the polluted wastewater at a rate of 5 liters and 10 liters...

Abstract

The present application discloses a composition for removing heavy metal Cd in water and its preparation method and application. Water-based fatty acid ethyl ester suspoemulsion and silicon-rich solution are measured at a volume ratio of 1:100 to 100:1, and the measured Water-based fatty acid ethyl ester suspoemulsion and silicon-rich solution are put into a reaction kettle with a stirrer, and at normal temperature, stir at 50-100r / min for 30min-14 days to prepare a composition for removing heavy metal Cd in water, providing high-efficiency The preparation method of the composition for removing heavy metal Cd in water body, environment-friendly and safe is used for purifying cadmium-polluted water. The final product can be used to purify natural and industrially polluted water. The final product can be separated from the water surface for combustion or used as diesel fuel. The ash produced by this process contains high content of cadmium, so it can be used as a raw material for the production of heavy metal cadmium to realize recycling industry, which is an environmentally friendly method.

Description

technical field [0001] The invention belongs to the technical field of purifying industrial or natural water polluted by cadmium, and particularly relates to a composition for removing heavy metal Cd in water bodies and its preparation method and application. The final product has a high positive effect on removing soluble cadmium in natural water and waste water. influences. Background technique [0002] Cadmium, Cd, is a highly toxic substance with toxic biological effects at concentrations smaller than those of almost any common mineral. The mechanism of cadmium toxicity may be multifactorial. Cd produces toxicity by directly or indirectly affecting the functions of various systems and tissue cells, such as bone, respiratory and urinary, cardiovascular, gastrointestinal and nervous systems. These toxic effects can lead to cell degeneration and even deformation. [0003] Due to its ubiquity, cadmium is easily dissolved and transported in water and has become an importan...
