DEVELOPMENT OF EFFECTIVE CLAY ADSORBENTS FOR CLEANING FATTY ACIDS OBTAINED FROM COTTON
Abstract
This article shows the possibility of purification of fatty acids by local clay adsorbents.The physicochemical properties of local clays have been studied.The carried out researches show that the sorbent obtained from the methods of sulfuric acid activation of Navbakhar alkaline bentonite, which mainly consists of montmorillonite mineral, is the most effective of the considered clay adsorbents.Its high sorption ability is provided by sulfuric acid activation, which develops internal pore volumes, especially with micro-sizes.It was found that the thermal activation of Angren kaolin does not give the desired degree of purification of fatty acids from the above impurities.The regularities of the processes of clarification and removal of residual metals from fatty acids on selected adsorbents have been established, and the optimal conditions for their implementation have been determined.
