New dithiophosphonate complexes of nickel, cadmium, mercury and lead.
This study was primarily focused on the synthesis and structural X-ray crystallographic analyses of new complexes. The work undertaken investigated the reactivity of the diphosphetane disulfide dimer, [P(4-C6H4OEt)S(S)]2, ...
Amperometric determination of selected persistent organic pollutants and heavy metals using horseradish peroxidase biosensor.
Persistent organic pollutants and heavy metals are released into the environment through different anthropogenic processes. They are of concern because they tend to bioaccumulate in the food chain and show adverse health ...
Physico-chemical analysis of transformer oil and stability studies of their blends with synthetic and natural antioxidants.
This study is focused on the analysis of transformer oil commonly used in South African transformers and the characterisation of the blends of these oils with either synthetic antioxidants or those extracted from natural ...
Metallic nanoparticle-graphene quantum dot nanocomposites for the electrochemical detection of methyl parathion.
This work reports on the detection of methyl parathion (MP) on electrodes constructed or decorated with graphene based nanomaterials. The sensing nanomaterials used include graphene quantum dots (GQDs), metal oxide [(MO): ...
A comparative study of solvent extraction, Soxhlet extraction, steam distillation, headspace analysis and headspace solid phase microextraction for the extraction of volatile terpenoid compounds in the curry leaf plant (Murraya koenigii).
A comparative study was undertaken of different extraction methods for the isolation of volatile organic compounds from Murraya koenigii (curry leaf plant). The techniques studied included the traditional methods of ...
