A mixture of acrylamide (AAm) and methacrylic acid (MAA) was crosslinked onto Gum ghatti (Gg) using N, N’-methylene-bis-acrylamide (MBA) as a crosslinker and ascorbic acid (ABC) and potassium persulphate (KPS) redox pair as an initiator. Optimized reaction parameters for the graft copolymerization of Gum ghatti with AAm were time (min)=90; temperature (C)=50; pH=7.0; deionized water (ml)=10; mo...

Abstract Soil erosion is a major environmental threat. The purpose of this study was to develop new polymer soil improvers that could mitigate the risk by modifying microstructure and improving ecological self‐repair ability. In particular, investigated composites (ADNB) based on different combination ratios nano‐aqueous adhesive (NAB) superabsorbent resin (SARn). effects types ADNB water chara...

Iodine preparations for external use are recommended for treating pressure ulcers with manifestations of infection and necrosis. These ulcers abundantly produce wound exudates, which could be absorbed by water-soluble base. In this study we aimed to improve the previously reported methodologies for water absorption and new methodologies were developed in Franz diffusion cell with 100kDa molecul...

Detection and quantification of pathogens in water is critical for the protection of human health and for drinking water safety and security. When the pathogen concentrations are low, large sample volumes (several liters) are needed to achieve reliable quantitative results. However, most microbial identification methods utilize relatively small sample volumes. As a consequence, a concentration ...

BACKGROUND Transcatheter arterial chemoembolization (TACE) is the standard treatment in selected patients with unresectable hepatocellular carcinoma (HCC). Drug-eluting particles are developed to reduce side effects and improve efficacy. We present safety data of a prospective randomized phase II study with doxorubicin-eluting superabsorbent polymer (SAP) microspheres. MATERIAL AND METHODS We...

A new approach to odor and pH control in medical and hygiene care applications relies on a treatment of absorbent fluff with selected enzyme inhibitors. Cellulose fiber was found to be a convenient carrier for some chemicals which modify the structure of an enzyme and/or block its active site. In an absorbent system exposed for example to body liquids containing urea, selected substances, when ...

A novel pH-responsive superabsorbent hydrogel based on gelatin was prepared through crosslinking copolymerization of poly (acrylic acid) and poly (itaconic acid). The copolymerization conditions including monomers, initiator, gelatin and crosslinker concentration, reaction temperature, and neutralization percent were systematically optimized to achieve a hydrogel with swelling capacity as high ...

The deficiency of water sources and the environmental disposal large amounts biomass waste (orange peels) produces economic problems, though its conversion into biochar by a pyrolysis procedure might be used to improve soil productivity. In current study, we investigated performance superabsorbent composite grafted on CMC as low-cost, alternative, biodegradable terpolymer (IPNCB) for retention ...
