A review on the applications of zinc tungstate (ZnWO) photocatalyst for wastewater treatment.

The monoclinic wolframite-phase structure of ZnWO materials has been frequently synthesised, characterised, and applied in optical fibres, environmental decontamination, electrochemistry, photonics, catalysis, and not limited to magnetic applications. However, the problems of crystal growth conditions and mechanisms, growth, the crystal quality, stability, and the role of synthesis parameters of ZnWO nanoparticles remain a challenge limiting its commercial applications. This review presents recent advances of ZnWO as an advanced multi-functional material for Industrial wastewater treatment.

The Occurrence of -nitrosodimethylamine (NDMA) in Swimming Pools: An Overview.

The occurrence of several disinfectant byproducts has been investigated in swimming pools. Until now, there are only a few studies on nitrosamine, particularly -nitrosodimethylamine in swimming pool water. This could be due to the lack of a suitable method that is sensitive enough for the measurement of -nitrosodimethylamine in pool waters.

Effects of aspect ratio of multi-walled carbon nanotubes on coal washery waste water treatment.

The dependency of adsorption behaviour on the aspect ratio of multi-walled carbon nanotubes (MWCNTs) has been explored. In this study, effect of growth temperature on yield and aspect ratio of MWCNTs by catalytic chemical vapour deposition (CCVD) method is reported. The result revealed that yield and aspect ratio of synthesised MWCNTs strongly depend on the growth temperature during CCVD operation.
