Photocatalytic Degradation of Dyes in Wastewater Using Solar Enhanced Nickel Oxide (NiO) Nanocatalysts Prepared by Chemical Methods.

This study examined the surface morphology and photocatalytic activity of nickel oxide (NiO) nanoparticles prepared through a chemical method. The synthesized nanoparticle was characterized by using spectroscopic and microscopic techniques. Photocatalytic degradation of hazardous Eriochrome Black T (EBT) was carried out using the synthesized nanoparticle and the efficiency of the NiO used was determined.

A Review on Nanomaterial as Photocatalysts for Degradation of Organic Pollutants.

Eliminating hazardous organic contaminants from water is a major concern today. Nanomaterials with their textural features, large surface area, electrical conductivity, and magnetic properties make them efficient for the removal and photocatalytic degradation of organic pollutants. The reaction mechanisms of the photocatalytic oxidation of common organic pollutants were critically examined.

Evaluation of physicochemical properties and heavy metal speciation of groundwater in Ifetedo and Garage Olode, Osun State, Nigeria.

To a large extent, public health can be prevented from being compromised by having access to potable water whose physicochemical fingerprints conform to the WHO Guidelines for drinking water. This study was carried out to assess the physicochemical properties and heavy metals speciation of groundwater in Nigeria. Water samples from thirteen sites were collected for three months and analysed for levels of pH, conductivity, nitrate, sulphate, phosphate, and heavy metals using standard methods.

Determination of polycyclic aromatic hydrocarbons and potentially toxic metals in commonly consumed beef sausage roll products in Nigeria.

Levels of polycyclic aromatic hydrocarbons (PAHs) and potentially toxic metals (PTMs) were determined in the commonly consumed beef sausage roll products (coded BS1 - BS6) in Nigeria. This was done in order to assess the safety of regular consumption of these products with respect to the substances determined. Three batches of six samples of beef sausage roll products were collected from Ile-Ife, Osun sate, Nigeria.
