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...
nanocrystalline titanium (iv) oxide paste has been deposited on fluorine doped tin oxide glass substrate by the blade method. the deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. the electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. avaspec 2.1 spectrophotometer was used to obtain the ...
Abstract Introduction: Dye effluents of some industries contain many toxic, carcinogenic, and mutagenic compounds therefore, wastewater colored contaminants of such industries should be meticulously refined using an appropriate method before discharging waste-water to the environment. Therefore, this study aimed to evaluate the effectiveness of Multi-Walled Carbon Nanotubes (MWCNTS) in dye r...
ZnO and TiO2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. Dye-modified ZnO and TiO2 showed significantly higher photocatalytic activity than neat ZnO and TiO2 under visible light illumination. Moreover, the prepared dye-modified ZnO showed superior photocatalytic efficiency in degrad...
in this research, the removal of malachite green dye from textile wastewaters using polyaniline coated onto sawdust (pani/sd) has been investigated. ammonium peroxodisulphate was used as chemical oxidant for polymerization of polyaniline directly on the surface of sawdust. the effects of some important parameters such as ph, initial concentration, sorbent dosage, exposure time and temperature o...
Myofibril-bound creatine kinase EC 2.7.3.2 (CK), a key enzyme of muscle energy metabolism, has been selected for studies of conformational changes that underlie the cellular control of enzyme activity. For fluorescence spectroscopy measurements, the CK molecule was double-labeled with IAF (5-iodoacetamidofluorescein) and ErITC (erythrosin 5'-isothiocyanate). Measurement of fluorescence resonanc...
this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...
the clay crosslinked hydrogel nanocomposites were synthesized by graft copolymerization of acrylamide and itaconic acid in the presence of different amounts of laponite using ammonium persulfate and n,n,n',n'-tetramethylethylene diamine )temed) as a free radical initiator and catalyst, respectively. the xrd patterns of nanocomposites showed that the clay layers are completely exfolia...
biosorption of acidic dyes using the live fern azolla filliculoides was studied in a discontinuous system. dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?c and ph=7. it was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. also, type of dye has an ...
