Water pollution is one of the environmental challenges to be surmounted avoid global public health hazard. Due complex chemical structure, azo dyes in industrial effluent have a long shelf life and are toxic aquatic creatures even at low quantities. In this study, decolourisation dye, methylene blue (MB) using locally sourced photocatalyst, eggshell ash (ESA) under solar ultra-violet (UV) radia...

Early detection of drug resistance in Mycobacterium tuberculosis isolates allows for earlier and more effective treatment of patients. The aim of this study was to investigate the performance of the malachite green decolourisation assay (MGDA) in detecting isoniazid (INH) and rifampicin (RIF) resistance in M. tuberculosis clinical isolates. Fifty M. tuberculosis isolates, including 19 multidrug...

Presence of colour in water will make it unsuitable for human consumption. Textile industries have the major role in imparting colour in natural water bodies as their outlets are opened to them. These industries rely upon azo dyes as it impart brilliant colour to fabrics. But its presence in water bodies creates serious problems. Structure of an azo compound is a very important factor to be con...

The photo-degradation of organic dye C.I. Acid Red 213 (AR-213) was achieved by 207 nm UV radiation emitted from a planar KrBr* excimer lamp without addition of oxidants at varying initial pH values. Precipitates were found to be generated when the irradiated solution of initial acid pH was adjusted to alkaline pH and they would disappear again when the solution was readjusted to acidic conditi...
