UV/Ni–TiO2 nanocatalyst for electrochemical removal of dyes considering operating costs

Multielectrode Teflon electrochemical nanocatalyst investigation system

The most common approach in the search for the optimal low temperature fuel cell catalyst remains "trial and error". Therefore, large numbers of different potential catalytic materials need to be screened. The well-established and most commonly used method for testing catalytic electrochemical activity under well-defined hydrodynamics is still thin film rotating disc electrode (TF-RDE). Typical...

Colour Removal of Three Reactive Dyes by Uv Light Exposure 1 after Electrochemical Treatment

Removal of dyes using low cost adsorbents

The low cost adsorbents namely Rice Husk Carbon (RHC), Wheat Straw Carbon (WSC) and Saw Dust Carbon (SDC) have been tested for the effectiveness in decolourisation of wastewater containing a mixture of dyes. Three dyes namely crystal violet, direct orange and magenta have been used for imparting colour in the representative samples of wastewater. Effect of various parameters such as agitation t...

Removal of Triphenylmethane Dyes by Bacterial Consortium

A new consortium of four bacterial isolates (Agrobacterium radiobacter; Bacillus spp.; Sphingomonas paucimobilis, and Aeromonas hydrophila)-(CM-4) was used to degrade and to decolorize triphenylmethane dyes. All bacteria were isolated from activated sludge extracted from a wastewater treatment station of a dyeing industry plant. Individual bacterial isolates exhibited a remarkable color-removal...

Structural Modifications of Surfactant-Assisted Alumina and Their Effectiveness for the Removal of Dyes

The current study focuses on the development of the modified surface of the alumina by anionic surfactant sodium dodecyl sulfate. The synthesized Surfactant Modified Alumina (SMA) effectively associated with dye molecules and amended their properties. The triphenylmethane (CBB) and thiazine dyes (MB) were selected as a simulated dye wastewater system. The removal was carried out by adsorpti...
