Refinery carbonatation is widely practised in South Africa and about 80% of the refined sugar produced in South Africa is clarified/decolourised using this method. Attempts have therefore been made to optimise the carbonatation process with regard to impurity removal. Some of the main factors that have been investigated to improve the decolourisation and filterability of the carbonated liquor a...

Textile effluents are among the most difficult-to-treat wastewaters, due to their considerable amount of recalcitrant and toxic substances. Fungal biosorption is viewed as a valuable additional treatment for removing pollutants from textile wastewaters. In this study the efficiency of Cunninghamella elegans biomass in terms of contaminants, COD and toxicity reduction was tested against textile ...

Novel rutin-loaded zein-sodium caseinate nanoparticles (ZP) with antioxidant activity in aqueous medium were investigated. The results showed that the sodium caseinate concentrations, dosages of rutin and ethanol volume fractions significantly affected the zein nanoparticles' characteristics. Concerning the antioxidant properties, the highest values of rutin loaded ZP obtained using 2, 2-diphen...

Production of manganese-dependent peroxidase (MnP) by the white-rot fungus Phanerochaete chrysosporium BKMF-1767 (ATCC 24725) was monitored during growth in different media and growth conditions. The effect of some activators of MnP production, Mn, Tween 80, phenylmethylsulphonylfloride (PMSF), oxygen, temperature, pH, glycerol and nitrogen was studied. Supplementing the cultures with Tween 80 ...

A novel and rapid and continuous hydrothermal route to the synthesis of extensive ultra-thin 2D sodium titanate (Na(2)Ti(3)O(7)) nano-sheets using a superheated water flow at 450 degrees C and 24.1 MPa as a crystallizing medium is described. High resolution electron microscopy of the sheets revealed that they were a few layers thick and largely uncurled, highly crystalline despite their very sh...

The economic development of any nation leads to the depletion its natural resources, and water is one them. Water pollution caused by various industries like food, leather, textile etc. causes severe impacts on environment humans. To ensure availability whole world, contaminated released from industries, mainly fabric, must be treated reused. conventional techniques alone are not enough treat e...

Background: It has long been recognized that the presence of azo metal complex dyes and their non-complexed counterparts in wastewaters, which is due to manufacturing use textile industries, renders natural waterways intensely coloured, therefore aesthetically unacceptable. Azo dye moieties are also known be precursors human carcinogenicity. Objective: This work aimed at decolourisation metal-a...
