Preparation method of high-adsorption-capacity water treatment agent

Abstract

The invention discloses a preparation method of a high-adsorption-capacity water treatment agent. The preparation method comprises the following steps that corncob powder is fed into tartaric acid for soaking, microwave irradiation treatment is performed, and filtration is performed to obtain a first pre-prepared material; vermiculite power, lauryl sodium sulfate, cocamidopropyl betaine and water are mixed evenly, heating is performed in a water bath, ultrasonic dispersion is performed, a succinimide solution is added, the pH value of a system is regulated with hydrochloric acid to 7.1-7.4, microcrystalline cellulose is added for stirring, suction filtration is performed, washing is performed to reach a neutral state, and drying and grinding are performed to obtain a second pre-prepared material; absolute ethyl alcohol and toluene are evenly stirred, the first pre-prepared material, the second pre-prepared material and methyltriethoxysilane are added, heating and stirring are performed, centrifugation is performed, flushing is performed with deionized water to make pH value neutral, and drying and smashing are performed to obtain the high-adsorption-capacity water treatment agent. The obtained high-adsorption-capacity water treatment agent is large in adsorption capacity and good in hydrophilcity.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method for preparing a water treatment agent with high adsorption capacity. Background technique [0002] The global shortage of water resources has attracted great attention all over the world. With the continuous development of our country's economy, the environmental burden is also increasing, and the problem of environmental pollution has become an urgent problem to be solved in our country. However, my country's industrial water consumption is astonishingly wasted. The main reason is that the reuse rate of industrial water is low. Therefore, improving the utilization efficiency of industrial or civil circulating water and adopting environmentally friendly water treatment agents are crucial to saving water resources, reducing production costs and protecting the environment. The environment is very important. Due to the high cost of preparation of water treatment ag...

However, my country's industrial water consumption is astonishingly wasted. The main reason is that the reuse rate of industrial water is low. Therefore, improving the utilization efficiency of industrial or civil circulating water and adopting environmentally friendly water treatment agents are crucial to saving water resources, reducing production costs and protecting the environment. environment is very important

Due to the high cost of preparation of water treatment agents, the adsorption activity of the heavily polluted fuel industry cannot meet the demand, and it needs to be solved urgently.
