Abstract The production of environmentally friendly SAP using biodegradable natural resources such as chitosan was synthesized for water saving and controlled-released fertilizer. Chitosan-g-poly(acrylamide)/attapulgite superabsorbent composites (CTS) were created by crosslinking N , '-methylene-bis-acrylamide (MBA) with (Ch), acrylamide, attapulgite (ATP) initiating the reaction potassium pers...

An elaborate surface-crosslinking method was introduced to enhance the low absorbency under load (AUL) and liquid permeability of itaconic-acid-based superabsorbent polymer (SAP). The effects reaction parameters absorption properties SAP were investigated. increase in content distilled water 1,4-butanediol used as solution improved AUL SAP, whereas an resulted a sharp decrease centrifuge retent...

Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...

Drought stress is one of the main restrictions in plant production in arid and semi-arid regions. Adding superabsorbent agents that maintain water in the soil, is among strategies to cope with drought stress. Therefore, in order to investigate the effect of zeolite superabsorbent on the physiological properties of carrot plants, the experiment was carried out as a factorial in a completely rand...

Propolis is a resinous product collected by honeybees with complex chemical composition. Sodium carboxymethylcellulose polymer commonly used in wound care. The goal of the present work was to produce and characterize NaCMC membranes loaded extract Brazilian brown propolis (CMC-P). Flavonoids phenolic acids were identified extracts, where main substance kaempferide. extracted active against S. a...
