Water management is rapidly becoming one of the most pressing issues facing all countries in semi-arid and arid parts world. Global water consumption predicted to increase by 50% 2030, resulting an acute shortage. Presently, agricultural sector consumes more than 70% freshwater regions world, putting pressure on scarcity. Hydrogels are superabsorbent polymers that can hold plant nutrients when ...

In arid areas, the rapid evaporation of water leads to severe shortage for plant growth. Superabsorbent polymers have prospect preventing because its excellent absorbency. However, insufficient in salt resistance, retention, and swelling rate limit application. Herein, we fabricated Hydroxyethyl cellulose-g-(Acrylic acid-co-2-Acrylamido-2-methyl-1-propane sulfonic acid)/laterite (HEC-g-P (AA-co...

Post-disturbance rangeland restoration efforts are often thwarted due to soil moisture deficits. Superabsorbent polymers (SAPs) absorb hundreds of times their weight in water, increasing when the SAP is mixed with soil. The objective this study was evaluate banded SAPs under surface increase plant available water and thus seedling establishment for perennial species during efforts. Five glassho...

conventional processes of food dewatering, such as thermal, have undesirable and destruction effects on vitamins, aromatic compounds and pigments. in addition, they are accompanied with some technological complications and energy consumption. thus, food concentration processes are directed to non-thermal techniques or methods with reduced heat effects. superabsorbents are highly hydrophilic pol...

introduction reduced availability of water resources in many arid countries including iran, particularly in response to the indiscriminate harvesting of water reservoirs and climate change, has created concerns. therefore, the sustainable use of water resources especially in agriculture is a necessity for these countries. strategies such as deficit irrigation and superabsorbent application are ...

Foreign body ingestion is a potentially serious clinical problem in children. We report a case of an 8-month-old infant who developed complete bowel obstruction requiring laparotomy due to ingestion of a superabsorbent polymer ball with advertised growth up to 400 times its original size. Most ingested foreign bodies that pass through the pylorus will make it safely through the gastrointestinal...

Tel.: +86-451-8219-1693 An antimicrobial superabsorbent was prepared by grafting polyacrylic acid on tara gum and adding chitosan quaternary ammonium salt (2-NHydroxypropyl-3-trimethylammonium chloride chitosan, HTCC). The effect of the amount of HTCC on swelling ratio of the product was investigated. The product was characterized by Fourier transform infrared (FTIR) spectroscopy, scanning elec...
