Almond green hull, an agriculture solid waste, was chemically treated and used for the adsorption of Co (II) from aqueous solutions. The efficiency of this new adsorbent was studied using batch adsorption technique under different experimental conditions such as sorbent amount, initial metal-ion concentration, contact time, adsorbent particle size, and chemical treatment. Optimum dose of sorben...

The adsorption of human immunoglobulin G (hIgG) and bovine serum albumin (BSA) on cellulose supports were investigated. The dynamics and extent of related adsorption processes were monitored by surface plasmon resonance (SPR) and quartz crystal microbalance with dissipation monitoring (QCM-D). Amine groups were installed on the cellulose substrate by adsorption of chitosan from aqueous solution...

cadmium (cd) concentration in soil solution and its bioavailability is controlled by sorption-desorption reactions. the objective of this research was to compare cd adsorption behavior in six calcareous and four acid soils. soil samples were equilibrated with 0.01 m ca(no3)2 containing 25 to 3200 mg cd l−1. results showed that the tendency for adsorption was high at low cd concentrations (0-400...

The aim of the present work was to investigate the feasibility of Kattamanakku tree leaf powder carbon (KTC) for Acid Red-114 (AR-114) adsorption. The adsorption of AR-114 on KTC material was studied as a function of KTC dose (0.05-1.20g). , solution pH 3-10, contact time and initial concentration (70-380 mg/l)., The influence of these parameters on the adsorption capacity was studied using the...

Novel reusable magnetic carbon microspheres (MCMs) were prepared by hydrothermal method with glucose as carbon source and Fe3O4 nanoparticles as magnetic raw materials. And adsorption performance of MCMs for sulfonamide removal from water was investigated in detail. The results indicated that the calcination temperature and calcination time had significant effects on the surface area and its vo...

Sawdust is obtained from naturally and easily available which is biodegradable. The bio sorption capacity of the sawdust for hexavalent chromium was studied at different solution pH values (1.5-6), initial metal concentration (50450 mg/L), adsorbent dose (1-7 g/L). The maximum adsorption of Cr (VI) is obtained at pH 1.5, initial concentration 50 ppm and adsorbent dose 5 g/l. The adsorption of c...

The natural estrogen 17β-estradiol (E2) is one of the known endocrine disrupting chemicals (EDCs) that have been entering water systems via human and animal waste products. The adsorption kinetics and thermodynamics of nylon membranes used in a filter for the removal of 17β-estradiol (E2) in water were studied. Experimental results showed that a linear adsorption isotherm was applicable over th...

Diazepam ingestion along with ethanol is encountered commonly in drug overdose cases. In the present study, the effect of pH and ethanol on the adsorption of diazepam in the simulated gastric fluid and the simulated intestinal fluid onto activated charcoal was determined in vitro. The adsorption behaviors of diazepam in both simulated gastric and intestinal pH onto activated charcoal were studi...

This study examined different methodologies to modify activated carbon (AC) for the removal of quaternary amine, tetramethylammonium hydroxide (TMAH), from water. Commercial carbon (WAC) was treated by nitric acid oxidation (NA-WAC), silica impregnation (SM-WAC0.5), and oxygen plasma (P10-WAC), and their characteristics and adsorption capacity were compared. The Langmuir model fitted the equili...

A hierarchical porous carbon obtained from pig bone (HPC) was utilized as the adsorbent for removal of Cr(VI) from aqueous solution. The effects of solution pH value, concentration of Cr(VI), and adsorption temperature on the removal of Cr(VI) were investigated. The experimental data of the HPC fitted well with the Langmuir isotherm and its adsorption kinetic followed pseudo-second order model....
