Sorption of Uranium Ions from Their Aqueous Solution by Resins Containing Nanomagnetite Particles

Removal of Copper from Aqueous Solution by Ion Exchange Resins

Sorption of dye from aqueous solution by peat

The sorption of two dyes, namely, Basic BIue 69 and Acid Bhre 25 onto peat has been studied in terms of pseudo-second order and first order mechanisms for chemical sorption as vrell as an intraparticle diffusion mechani!jm process. The batch sorption process, based on the assumption of a pseudo-second order mechanism, has been developed to predict the rite constant of sorption. the equ~lib~um c...

Biosorption of Uranium (VI) from Aqueous Solution by Pretreated Aspergillus niger Using Sodium Hydroxide

The removal of uranium and any other heavy metals from wastewater might be achieved via several chemical or physical treatment techniques. Biosorption process has been considered as a potential alternative way to remove contaminants from industrial effluents. Moreover the surface of biosorbent was characterized by SEM. The biosorption characteristics of uranium (VI) on pretreated A...

Reactive Dye Removal from Aqueous Solution by Sorption

* E-mail: [email protected] ABSTRACT Effluents of textile dyeing are characterized by intense colour, chemical oxygen demand, suspended solids and a variety of refractory matter, such as heavy metals and nonionic surfactants. Strong colours may reduce light penetration, thus affecting the growth of plants and having impact on invertebrate and other forms of wildlife. There are a large numbe...

Adsorption of Lead ions from aqueous solution by the dead biomass of nanoalgae Scenedesmus sp.

In attempts to remove toxic metal lead, distinct types of algae biomass have been scrutinized as alternatives to conventional physicochemical technologies. In this research, the absorption of  Lead by nanoalgae Scenedesmus sp. was studied at concentration of10 to 100 mg/L, pH 3 to 8, temperature 15 to 40 °C and exposure time of 10 to 60 minutes)in a batch culture system. The concentration of Le...
