In this study Ceramium virgatum has been characterized and used for the removal of cadmium and lead from aqueous solutions. The effect of pH, adsorbent dosage, contact time and temperature on adsorption process was studied in batch experiments. Langmuir and Freundlich models were applied to describe the biosorption isotherm of the metal ions by C. virgatum biomass. The adsorption data can be we...

This research article deals with an electrosynthesis of hydrous titanium dioxide by anodic dissolution of titanium sacrificial anodes and their application for the adsorption of manganese from aqueous solution. Titanium sheet was used as the sacrificial anode and galvanized iron sheet was used as the cathode. The optimization of different experimental parameters like initial ion concentration, ...

The development of a country depends on industrialization and agricultural production. Due to this number of industries and factories like metal industries, dyeing, fertilizers, painting industries are coming continuously which creates severe environmental pollution especially water problem should be created and also cause global warming. To controlling of environmental pollution is very big ch...

Arsenic contamination in water poses a serious threat on human health. The tea fungus known as Kombucha is a waste produced during black tea fermentation. The objective of this study was to examine the main aspect of a possible strategy for the removal of arsenates employing tea fungal biomass. The pretreatment of biomass with FeCl3 was found to improve the biosorption efficiency. Arsenics upta...

C-phycocyanin is a natural blue dye extracted from Spirulina platensis, which has many applications in the food and pharmaceutical industries. In this paper the effect of pH and temperature on the adsorption of C-phycocyanin onto two different ion exchange resins (Streamline DEAE and Streamline Q XL) for expanded bed adsorption chromatography was investigated. Moreover, the kinetics and adsorpt...

In this study, durian (Durio zibethinus Murray) skin was examined for its ability to remove methylene blue (MB) dye from simulated textile wastewater. Adsorption equilibrium and kinetics of MB removal from aqueous solutions at different parametric conditions such as different initial concentrations (2-10 mg/L), biosorbent dosages (0.3-0.7 g) and pH solution (4-9) onto durian skin were studied u...

The extraction of cellulose from sisal fiber was done initially using the steam explosion method. Extracted cellulose was grafted with acrylic acid in the presence of ceric ammonium nitrate redox initiator. The grafting phenomenon taking place between cellulose and the acrylic acid was proved by Fourier transform infrared spectroscopy (FTIR). The prepared graft copolymer was used as adsorbent f...

Agricultural solid waste (corn cob) has been investigated asbiosorbent for removal of metribuzin herbicide from aqueous solution. Parameters influencing extraction efficiency such as pH of the sample, contact time of sample with biosorbent, shaking time, temperature, heating time, sorbent dose were studied. Maximum sorption of metribuzinwas found at pH 5.0. The sorption of metribuzin on corn co...
