During the last decade, public concern over carbamate pesticide residues has increased remarkably and their accurate determination in environmental samples is gaining great importance. These compounds are present in environmental samples at low conce... Read More about Development of a microfluidic approach to the analysis of carbamate pesticides in drinking water.

Fabrication, functionalization and characterization of silica monolith for forensic chemistry applications (2014)
Thesis
Khattab, A. K. Fabrication, functionalization and characterization of silica monolith for forensic chemistry applications. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4216084

The physiochemical properties of silica monolith make it an ideal base material for drugs extracting, pre-concentrating and separation from biological samples which can interact not only with molecules but also with ions and atoms. However, the fabri... Read More about Fabrication, functionalization and characterization of silica monolith for forensic chemistry applications.

Amperometric measurement of gaseous hydrogen sulfide via a Clark-type approach (2010)
Journal Article
Horn, J. J., Wadhawan, J., & Mccreedy, T. (2010). Amperometric measurement of gaseous hydrogen sulfide via a Clark-type approach. Analytical Methods, 2(9), 1346-1354. https://doi.org/10.1039/c0ay00338g

The direct oxidation of hydrogen sulfide in the range 2.0-20 parts per million by volume (ppmv) using a Clark-type amperometric gas sensing methodology is investigated via amperometric transients at 298 K. The diluent gas employed is air (20.9% O-2 i... Read More about Amperometric measurement of gaseous hydrogen sulfide via a Clark-type approach.
