Sawdust a timber waste has been used as a bio-sorbent for the removal of a cationic dye, malachite green from aqueous solutions. The process of removal has been optimized for different parameters like initial concentration of dye solution and contact time, pH, adsorbent dose, and temperature. pHzpc of the adsorbent was determined. Elemental analysis of the adsorbent was carried out. FTIR was pe...

Plasma processing is demonstrated as a generic technology to fabricate, roughen, control the wetting properties, create well controlled passive hydrophobic valves, and finally also control the protein adsorption in polymeric microfluidic channels. Lithography and deep anisotropic O2 plasma etching directly on polymeric substrates were utilized to pattern microchannels, at conditions where very ...

The degradation and adsorption behavior of dibutyl phthalate (DBP) in methanogenic phase refuse was investigated through laboratory microcosm experiments. The results showed that the half-life of DBP in the sterilized refuse was 5.9 times higher than in unsterilized samples, but that it decreased by 35.8% when dominant bacterial strains were added. Different concentrations of DBP did not have o...

Biochar, as an high efficiency, environmental friendly, and low-cost adsorbent, is usually used as soil conditioner, bio-fuel, and carbon sequestration regent. Recently, biochar has attracted much attention in wastewater treatment field. There are plenty of studies about application of biochar to adsorb pollutants in wastewater, because of its low-cost preparation, high surface area, large pore...

This article deals with the interrelationship between overall chemical speciation of S, Fe, Co, and Ni in relation to metals bio-uptake processes in continuous stirred tank biogas reactors (CSTBR). To address this topic, laboratory CSTBRs digesting sulfur(S)-rich stillage, as well as full-scale CSTBRs treating sewage sludge and various combinations of organic wastes, termed co-digestion, were t...

Introduction: Using bio-sorbents is regarded as one of the effective methods to remove heavy metals. Therefore, this study aimed to investigate Pb adsorption from contaminated water by Chaetoceros sp. and Chlorella sp. algae. Methods: This experimental study was conducted in a batch reactor. The amount of Pb adsorption by Chaetoceros sp. and Chlorella sp. algae was studied under such conditio...

The purpose of this study is to investigate the adsorption characteristics granular aggregates under identical experimental conditions for potential applications in highly adsorptive concrete. In study, industrial by-products (steel slag), lightweight (expanded silica) and bio-materials (peach shell miscanthus) are used phosphorus (P) removal from aqueous solutions. effects several parameters s...

The co-production of bio-char and upgraded bio-oil by fast pyrolysis raw sulfuric-acid pretreated agro-industrial wastes (corn cob, sugarcane bagasse sunflower seed hull) was investigated to valorize as sources value-added products (VAPs) following the circular bio-economy system. To this end, proximate elemental analyses were performed, adsorption properties determined in products. Bio-char yi...
