Antibiotics Removal from Aqueous Solution and Pharmaceutical Wastewater by Adsorption Process: A Review

A Review on Diclofenac Removal from Aqueous Solution, Emphasizing on Adsorption Method

Diclofenac is a drug with an analgesic effect that accumulates and results in adverse consequences if it enters the human body more than needed. Low concentrations of diclofenac have been detected in different water sources through leachates of landfills and agricultural areas, human and animal excreta expired drug discharge and hospital effluents. To eliminate diclofenac from the aquatic e...

Removal of heavy metals from aqueous solution by sawdust adsorption.

The adsorption of lead, cadmium and nicel from aqueous solution by sawdust of walnut was investigated. The effect of contact time, initial metal ion concentration and temperature on metal ions removal has been studied. The equilibrium time was found to be of the order of 60 min. Kinetics fit pseudo first-order, second-order and intraparticle diffusion models, hence adsorption rate constants wer...

Silver Removal from Aqueous Solution by Adsorption on Concrete Particles

The major industrial use of silver is as silver halide in the manufacture of photographic film. In 1983, approximately 44% of silver was used in the manufacturing of chemicals for photographic products in the USA. Other industrial uses of silver include the production of electrical contacts and switching gear, batteries, catalysts and mirrors. It has also been used for jewelry, coins and indeli...

Removal of chromium (VI) from aqueous solution by adsorption using cousinia eryngioides boiss and activated carbon

Adsorption capacity of Cr (VI) onto cousinia eryngioides boiss, activated carbon was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH, temperature, agitation speed, absorbent dose and particle size. Cr (VI) removal is pH dependent and found to be maximum at pH 2.0. The amounts of Cr (VI) adsorbed increased with increase...
