BACKGROUND In this research, response surface methodology (RSM) was applied to optimize Reactive Blue 19 removal by activated carbon from pomegranate residual. A 24 full factorial central composite design (CCD) was applied to evaluate the effects of initial pH, adsorbent dose, initial dye concentration, and contact time on the dye removal efficiency. METHODOLOGY The activated carbon prepared ...

Athi tree leaves (Ficus relegiosa) powder carbon was used as an adsorbent for the removal of DNB-106 dye from an aqueous solution. The studies were carried out under various experimental conditions such as agitation time, dye concentration, adsorption dose, and pH to assess the potentiality of Athi leaves powder carbon (ATC) for the removal of DNB-106 dye from wastewater. A greater percentage o...

Rice husk carbon (RHC) has been prepared from rice husk impregnated with 50% H3P04 and carbonised at 300°C. Its adsorption capacity has been tested for the decolourization of wastewater containing safranine and methylene blue. The effect of system variables such as concentration, temperature, pH, contact time, adsorbent dosage and particle size are investigated. Removal of dye has been found to...

A new spectrophotometric method for the determination of palladium with Pyrogallol Red is described. Its high sensitivity is dependent on the presence of micellar system of 1-carbethoxypentadecyltrimethylammonium bromide, which leads to the maximum colour formation in acid solutions (pH 5.5) in a shorter time interval than in the absence of tenside. The ternary pal­ ladium-dye-cation-active ten...

A novel ternary composite (RGO-?CD-ECH) consisting of epichlorohydrin (ECH) cross-linked beta-cyclodextrin polymer (?CD-ECH) with reduced graphene oxide (RGO) as a carrier was synthesised and used for the removal malachite green (MG) dye from water. The adsorption performance systematically investigated in batch mode, optimised parameters were follows: initial MG concentration 100 mg/L, solutio...

In this paper, dye removal ability of the surface modified nanoparticle SMN copper ferrite from single and quaternary systems was investigated. Acid Blue 92 AB92, Direct Green 6 DG6, Direct Red 23 DR23 and Direct Red 80 DR80 were used as model compounds. The effect of surfactant concentration, adsorbent dosage, dye concentration and pH on dye removal was evaluated. The adsorption isotherm and k...

Cibacron Blue 3G-A (CB3G-A, I) was investigated as a ternary complex analogue of lactate dehydrogenase and phosphoglycerate kinase as had been suggested earlier (Stellwagen, E. (1977) Accts. Chem. Res. 10, 92-98). CB3G-A and Procion Brilliant Blue (PBB, II), a structural isomer of the Cibacron dye without the sulfonated benzoyl moiety, were attached covalently to Sepharose CL-6B. The two enzyme...
