background; recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. therefore, the aim of this study was to determine the feasibility of using lemna minor for acid blue 292 (ab292) dye removal from aqueous solution and to determine the optimal conditions. methods; this experiment...

background: there is unprecedented increase in the processing and packaging of many plant materials into food supplements, herbal medicine, skincare and cosmetic products for human needs. baphia nitida is used for topical skincare products. toluene, a toxic aromatic solvent, is increasingly being used in the production of these skincare and cosmetic products in many industries. this study asses...

the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...

in this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. the influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final ph and energy consumption rate was determined. dye removal was increased with increases in solution ph, current density and contact tim...

With the use of 2.1 M sucrose solution, nuclei were isolated from normal, control, and azo preneoplastic livers, and from azo dye-inducedliver tumors of rats. Four consecu tive extractions of nuclear sap in isotonic saline-phosphate buffer solubiized 49 and 37 per cent of the nitrogen of liver and tumor nuclei, respectively. Velocity sedimentation analyses revealed that the soluble nuclear macr...

The interaction of Toluidine blue with Sodium Alginate has been investigated by spectrophotometric method. The polymer induces metachromasy in the dye as evidenced from the considerable blue shift in the absorption maxima of the dye. The interaction constant and thermodynamic parameters of polymer-dye interaction have been determined. The effect of alcohols on the reversal of metachromasy has b...

The chromatographic behavior of a heterogeneous protein mixture and of a series of homogeneous proteins on the immobilized dye tetraiodofluorescein has been observed and analyzed. Less than 6%, of the millimolar concentration of dye immobilized to a porous agarose matrix is accessible to protein. The affinity of a protein for immobilized dye is dramatically increased by insertion of apolar spac...

The photocatalytic degradation of the chemical dye AZO and dye effluents in different time duration has been investigated using biologically synthesized silver nanoparticles. Dye industry effluents and AZO dye undergo degradation to form harmless intermediate and colourless products following irradiation by UV and solar light in the presence of green synthesized silver nanoparticles. The degree...

In order to test photoelectric recording of dye curves, simultaneous determinations of cardiac output were made in 48 patients with heart disease with the Fick and dye-dilution technics. The dye curves were recorded with a Colson densitometer following either intrathoracic or antecubital injection of dye. Both Evans blue and indoeyanine green dyes were employed. Satisfactory agreement was noted...
