Preparation and improvement of specifications of sodium polymer acrylates through the addition of bentonite to the treatment of desertification

Abstract

The phenomenon of desertification has a negative impact on the national economy of any country, and may usually be obtained for many reasons such as the removal of agricultural land, depletion of soil, overgrazing, poor irrigation methods, high temperature, and lack of rainfall. In this paper, we addressed the problem of lack of rainfall using chemical methods, by preparing sodium polyacrylate and improving its properties of via adding bentonite, thus obtaining a new and improved water absorption compound. We found that the suitable bentonite ratio is between (0 - 20 wt%) to ensure water absorption from 1340 gg - 1 to 1500gg - 1, in which we ensure that the cross-linked of the compound is not changed and the absorption of water is higher. The presence of Bentonite with polymer at perfect percentage has contributed to the reorganization of the distribution of granular size of the polymer sodium polyacrylate, which was reflected in the result of increasing its ability to absorb water and thus make it a suitable compound in the treatment of desertification.
