liquid-phases adsorption equilibrium of phenol onto two naturally available soils namely kalathur soil (kr) and adhanur soil (ar) were studied. the experimental data were analyzed using fourteen isotherm models, ranging from single-parametric model to multi-parametric models (up to 5 parameters) of the system. results show that in general the accuracy of models to fit experimental data improves...

The study attempted to determine suitable forecasting models predict primary rubber products along the supply chain in Thailand. Historical data used this were during years 1999–2021. Two techniques establish models, including stepwise multiple regression analysis and PCA. It was found that both quantities of natural rubber, smoked sheets, block concentrated latex. MAPEs for these four predicti...

Hydrogels based on a graft copolymer of acrylic acid (AA) and acrylamide (AAm) backbone starch, obtained from different natural sources, have been prepared characterized for potential agricultural use, as soil moisture regulators nutrient sources plant nutrition. Five types starch are used: corn, waxy wheat, potato, rice starch. by solution polymerization method, in the presence ammonium persul...
