Embodiment 1

[0014] A preparation method of white boron calcium petroleum ethyl ester composite modified bentonite, comprising the steps of:

[0015] (1) Ingredients: Take by weighing 160g of leucumite, 600g of ethyl oleate, and 900g of bentonite respectively;

[0016] (2) Mixing materials: mix bentonite and leucumite evenly, then add ethyl oleate and stir evenly;

[0017] (3) Reaction: Pour the mixed material into a high-temperature and high-pressure reactor, fill the reactor with inert gas and exhaust the air, adjust the pressure in the reactor to 3.2Mpa, and the temperature to 230°C, and place the reactor in an ultrasonic field. The frequency of the ultrasonic field is 32KHz, and the power density is 0.48w / cm 2 ;

[0018] (4) Drying: After reacting for 20mim, cool naturally to 75°C, pour the material out of the reaction kettle and spread it into an oven at 75°C, so that the unreacted ethyl oleate is volatilized, and then grind to a particle size smaller than 100 microns, that is.

Abstract

Disclosed is a preparation method of pandermite ethyl oleate compound modified bentonite. The method comprises the following steps that pandermite, ethyl oleate and bentonite are weighed according to the ratio of parts by weight being (5-10):(25-35):(40-50) for use; the bentonite and the pandermite are mixed to be uniform, and the ethyl oleate is added and stirred to be uniform; the mixed material is poured into a high temperature and high pressure reaction kettle, inert gas is introduced into the reaction kettle, air is exhausted, and the reaction kettle is placed into an ultrasonic field; after the reaction is performed for 15-30 min, natural cooling is performed, the unreacted ethyl oleate is volatilized thoroughly, and then grinding is performed to obtain the pandermite ethyl oleate compound modified bentonite. The pandermite ethyl oleate compound modified bentonite obtained through the method has the specific adsorptivity, dispersibility and rheological property of clay mineral, has polyfuncitonal groups and reaction activity of organic compounds and improves the adsorption effect.

Description

technical field [0001] The invention relates to a modification method of bentonite, in particular to a preparation method of white boron calcium petroleum ethyl ester composite modified bentonite. Background technique [0002] With the rapid development of industry and agriculture, a large number of industrial chemicals are discharged into rivers, lakes, seas and other water bodies, causing serious pollution to the water body environment and increasingly endangering the health of the people. At present, the problem of water pollution control has become one of the important problems that our government urgently needs to solve. The existing common methods of sewage treatment include physical chemical method, chemical method and biochemical method, but these methods are complicated in process, high in cost and low in efficiency. Studies have shown that using adsorbent materials to adsorb pollutants in sewage is an efficient and convenient treatment method to solve water enviro...
