The optimization of adsorption-based operations requires an accurate model to represent the separation process. In the present study, single-component adsorption data of L-lysine on its imprinted polymer were fitted to Freundlich, Langmuir-type and Jovanovic-type models. L-Lysine imprinted polymer (LLIP) was prepared by free radical solution polymerization. The best estimate of the parameters o...

Electron beam irradiated sheep wool dosed (0–410) kGy showing good adsorption properties was tested for Cr(III) and Co(II) of higher concentrations. Fitting to ten isotherm models examined as follows: Langmuir, Freundlich, Dubinin-Radushkevich, Temkin, Flory-Huggins, Halsey, Harkins-Jura, Jovanovic, Elovich Redlich-Peterson. Both cations being Lewis acids generate complex salts, such carboxylat...

Peat water source could be utilized to mitigate scarcity issues that are experienced by the local communities in Sarawak rural areas. However, this needs treated prior domestic consumption due levels of humic substances being incomparable Malaysia quality standards. As such, study aims formulate kinetic models for peat treatment with continuous electrocoagulation system using aluminium electrod...

Four silica samples were evaluated as supports in the hydroformylation of oct-1-ene by Supported Aqueous Phase Catalysis (SAPC) using [Rh2(μ-SBu)2(CO)2(TPPTS)2] and [Rh(COD)Cl]2/TPPTS as catalysts. Adsorption studies of the [Rh(COD)Cl]2/TPPTS complex from aqueous solutions on the supports were carried out at 25 °C. The isotherms obtained were correlated by several models, among which the Fowler...

UiO-66 (Zr-MOF) metal-organic framework was successfully synthesized by the solvothermal method and characterized using FTIR, PXRD TGA. Its ability to remove Malathion, 2,4-Dichlorophenoxyacetic acid (2,4-D) a mixture of two from an aqueous solution studied. Effects different experimental parameters (pH, adsorbent dose, contact time, speed agitation initial pesticide concentrations) were Adsorp...

The utilization of less expensive and more effective adsorbents derived from a variety basic materials has been investigated. research aimed to investigate the feasibility employing waste paper as adsorbent remove cresol red (CR) dye wastewater through adsorption mechanism. Langmuir, Jovanovic, Freundlich model were observed for isotherms models, while pseudo-first-order pseudo-second-order exa...

The economic viability of adsorbing crystal violet (CV) using pepper seed spent (PSS) as a biosorbent in an aqueous solution has been studied. A parametrical investigation was conducted considering parameters like initial concentration dye, time contact, pH value, and temperature variation. analysis experimental data obtained carried out by evaluating with the isotherms Freundlich, Sips, Tempki...
