Method for producing halloysite adsorbent, modified with hexadecyltrimethylammonium bromide, preferably for adsorption of phenol and its halogen derivatives

摘要

The purpose of this notification is to provide for the production of a haloside adsorbent modified with hexadecyl trimethylammonium bromide, in particular for the adsorption of phenol, 2 -chlorophenol, 3 -chlorophenol, 4 -chlorophenol, 2,4 -dichlorophenol and 2,4, 6 -Trichlorophenol from the water of the dried 10 -weight part of the haloisit mineral with the content of 15%of the weight water, which is split into the ball mill and separated by the diameter of the grains 0,4 -0,63 m m and 10 -weight parts and the resulting fraction is washed five times ten with the weight of distilled water. The way this works is,that ten parts of the aqueous solution of sodium chloride with a concentration of 15% of weight are added to the 5 -weight portion of the distilled water of the haloside mineral and are mixed by heating up for 24 h at temperature 313 K in a glass reactor with a mixture,and then decontaminate the solution from the haloside mineral and wash the haloside mineral with deionised water to remove chlorine ions by sampling with silver nitrate and add 20 -parts of the aqueous solution of hexadecyl trimethylammonium to the 5 -part weight of the haloside mineral that has been smuggled by the concentration of 2,5% of weight and is mixed at temperature 298 K through 24 h in a glass reactor with a mixture, and the haloist adsorbent obtained modified with hexadecyl trimethylammonium bromide is dried at temperature 298 K.
