The enzyme peroxidase is known for its capacity to remove phenolic compounds and aromatic amines from aqueous solutions and also to decolourize textile effluents. This study aims at evaluating the potential of a turnip (Brassica rapa) peroxidase (TP) preparation in the discolouration of textile azo dyes and effluents. An azo dye, Congo Red (CR), was used as a model pollutant for treatment by th...

A first-order derivative spectrophotometric method for the simultaneous determination of three textile dyes, Procion Yellow HE4R, Procion Red HE7B and Remazol Black 5 (RB5), has been developed. The effects of pH, heating and ionic strength of the solution on the absorption spectra of the dyes were investigated. The wavelengths selected for the measures of the derivative signals of HE4R (395 nm)...

Textile industry is one of the oldest and largest industries of India. Synthetic dyes are coloring agents mainly used in textile industries which generate a huge amount of wastewater in the process of dyeing. It is estimated that these industries discharge around 280,000 tons of dyes worldwide every year into the environment (Tom Sinoy and Anuradha Mohan, 2011). Discharge of these colored efflu...

One of the major problems encountered in the textile industry is the production of large volumes of highly coloured wastewater. The textile industries daily discharge million litres of untreated effluents in the form of wastewater into public drains that eventually empty into rivers. They cause serious health hazard. Textile wastewater also contains substantial pollution loads which increase th...

Comparative study of the removal of the dye Reactive Red 120 (RR-120) from aqueous effluents from textile industry using microalgae Spirulina platensis (SP) and commercial active carbon (AC) were carried out. The batch adsorption systems were evaluated with respect to pH, agitation time, temperature and initial concentration of the dye. The maximum adsorption capacity for dye RR-120 were found ...

In Rajasthan state particularly, textile mills represent an important economic sector. Pali district in Rajasthan has got largest number of textile industries in the State i.e.989 units, mostly engaged in cotton and synthetic textile printing and dyeing. These industries liberate a variety of chemicals, dyes, acids and alkalis besides other toxic compounds like heavy metals, which are known for...

the present study has been undertaken in a laboratory scale to characterize and investigate pollution potential of textile effluents from depz area in dhaka, bangladesh. collected effluent samples from five different industries were analyzed for physico-chemical parameters using field kits and standard methods, and for metals using flame atomic absorption spectrophotometer (faas). the average p...
