New dithiophosphonate complexes of nickel, cadmium, mercury and lead.
(2013)
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.
(2010)
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.
(2012)
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.
(2017)
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).
(2010)
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 ...
