in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

the analytical theory of one dimensional, dispersion free miscible displacement of oil by injection gas with nc component has shown that: the mmp is the lowest pressure at which any one of the initial oil, injection gas or crossover key tie lines becomes critical, which means that its length approaches to zero. in this paper, we propose a method for a solving multi component system based on ana...

This study investigated the efficiency of electerocoagulation (EC) in removing color from synthetic and simulated textile wastewater. The study on decolorization of mixed dyes is a step toward an effective treatment of textile wastewater. Two representative reactive dye molecules were selected for the synthetic dye wastewater, a blue dye alone and mixed dye (black, blue, red, 1:1:1v/v). The EC ...

A ternary nanostructured photocatalyst consisting of ZnO/TiO2/Au was designed to achieve an enhanced solar absorption due to the coupling of surface enhanced plasmonic absorption of metal and semiconductor excitons. TiO2 coated ZnO rods with an aspect ratio of 8-12 were decorated with citrate capped gold nanoparticles for photocatalytic degradation of organic pollutants in simulated waste water...

The long-term performance of a submerged membrane fungi reactor was observed while a synthetic textile wastewater containing either or both of the two structurally different azo dyes was continuously fed. Compared to the Acid Orange II dye (simpler structure), higher biosorption but slower biodegradation of the polymeric dye (Poly S119) was observed in sterile batch tests. In the membrane biore...
