Statistical parameter optimization and modeling of photodegradation of methyl orange using a composite photocatalyst prepared by thermal synthesis.

Doping a transition metal into photocatalysts enhances the photocatalytic activity drastically. In the first part of this study, Taguchi design of experiment is applied to evaluate and optimize the efficiency of the FeO/TiO photocatalyst synthetized by thermal method assisted by UV radiation. The contribution percentages of Fe:TiO mass ratio, FeO/TiO dosage, and pH on the total organic carbon (TOC) removal are determined using analysis of variance (ANOVA).

Photocatalytic degradation of aqueous Methyl Orange using nitrogen-doped TiO photocatalyst prepared by novel method of ultraviolet-assisted thermal synthesis.

A nitrogen-doped titanium dioxide composite photocatalyst (N-TiO) with heterojunction structures is synthesized by three different approaches: a novel UV-assisted thermal synthesis, annealing, and microwave technique. Photocatalytic activities of synthesized photocatalysts are evaluated by the degradation of Methyl Orange under ultraviolet light types A (UV-A), B (UV-B), and C (UV-C), visible light, and direct sunlight irradiation. Results show that by using N-TiO photocatalyst prepared by the UV-assisted thermal synthesis and annealing, the degradation increases by 16.

Photocatalytic efficiency of FeO/TiO for the degradation of typical dyes in textile industries: Effects of calcination temperature and UV-assisted thermal synthesis.

The inadequate management practices in industrial textile effluents have a considerable negative impact on the environment and human health due to the indiscriminate release of dyes. Photocatalysis is one of the diverse advance oxidation processes (AOPs) and titanium dioxide (TiO) is recognized for its high oxidation and reduction power. A composite photocatalyst of FeO/TiO is synthesized using different mass ratios of Fe:TiO to improve its photoactivity.

Radioactivity and radiological risk associated with effluent sediment containing technologically enhanced naturally occurring radioactive materials in amang (tin tailings) processing industry.

The processing of amang, or tin tailings, for valuable minerals has been shown to technologically enhance NORM and this has stirred significant radiological safety and health concerns among Malaysia's regulatory authority. A growing radiological concern is now focused on the amang effluent containing NORM in recycling ponds, since these ponds may be reclaimed for future residential developments. A study was carried out to assess the radiological risk associated with amang processing and the accumulated effluent in the recycling ponds.
