An investigation was conducted on the adsorption of oxymatrine (OMT) on a spherical cellulose adsorbent embedded with wattle bark tannin. The results showed that the adsorption of the OMT on the adsorbent was solution pH dependent and the adsorption process followed the Freundlich adsorption isotherm. The adsorption kinetics of the OMT on the adsorbent could be well described by the pseudo-seco...
Silanized-glass-particle adsorbent capacities are extracted from adsorption isotherms of human serum albumin (HSA, 66 kDa), immunoglobulin G (IgG, 160 kDa), fibrinogen (Fib, 341 kDa), and immunoglobulin M (IgM, 1000 kDa) for adsorbent surface energies sampling the observable range of water wettability. Adsorbent capacity expressed as either mass-or-moles per-unit-adsorbent-area increases with p...
Methods of physical and chemical adsorption of heavy metals have disadvantages in some ways- such as high cost and ineffectiveness at low concentrations. In recent decades methods of biological uptake of heavy metals have been investigated. The biological adsorbents include bacteria, fungi and alga, among which algae have the highest efficiency of metal uptake. This study indicated that Alginic...
The present study was conducted for the removal of color of pulp and paper mill effluent using coal fly ash as an adsorbent. The effect of adsorbent dose and pH on color removal has been determined. 100 % color removal was achieved when adsorbent dose was 2.4 gm or more and at pH 6.8 and above.

An Adsorbent based treatment system is presented for toxic metal removal from rinsewater streams. The adsorbent is a Mg-A1 oxide anion exchange material with high capacity (approaching 5.5 meq/g) and strong selectivity for difficult to treat species such as Electroless plating metal chelates, Fixed Cyanides and chrome conversion solutions. Data is presented describing treatment of various metal...
Adsorption studies were conducted to determine whether adsorbent concentration (soil-solution ratio) affected insecticide adsorption by soils and clays. Adsorption isotherms were obtained for several insecticides in Bondhead sandy loam and Ca-saturated illite suspensions using adsorbent concentrations that were varied over several orders of magnitude. There was no evidence that altering adsorbe...
abstract mefenamic acid is a nonsteroidal anti-inflammatory drug (nsaid) that has analgesic,anti-infammatory and antipyretic actions. it is used to relieve mild to moderate pains. solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . poly allyl glycidyl ether/iminodiacetic acid-co-n, n-dimethylacrylamide was synthesized and grafted to silica gel and was used ...
Wastewaters obtained from fenvalerate manufacturing process were treated for its safe disposal using activated coconut shell carbon (acc) as adsorbent. In this work, the removal efficiency of organic matter in terms of chemical oxygen demand (COD) utilizing acc has been investigated. Various parameters which can influence the adsorption like adsorbent dosage, contact time of solution with adsor...
Introduction: The increasing environmental pollution by heavy metals caused serious concern due to the carcinogenicity non biodegradability, and biological accumulation properties. The purpose of this study was to investigate the removal of copper as a heavy metal by using camel bone powder from wastewater. Methods: The process of copper absorption by powdered camel bone was performed in l...
