Organophosphate and carbamate pesticides are powerful neurotoxins that impede the activity of cholinesterase enzyme leading to severe health effects. This study firstly reports the development, characterisation, and application of thick-film acetylcholinesterase (AChE) biosensors based on a gold electrode modified with a mercaptobenzothiazole (MBT) self-assembled monolayer and either poly(o-methoxyaniline) (POMA) or poly(2,5-dimethoxyaniline) (PDMA) in the presence of polystyrene(4-sulphonic acid) (PSSA). The Au/MBT/POMA-PSSA/AChE and Au/MBT/PDMA-PSSA/AChE biosensors were then applied to...

This book presents the results for the physical and chemical characterisation of co-disposal precipitates prepared from the co-disposal of acid mine drainage and fly ash. The prepared high capacity ion exchange adsorbents were characterised using fundamental characterisation tools such as X-ray Diffraction Spectrometry (XRD), X-ray Fluorescence Spectrometry (XRF), Scanning Electron Microscopy (SEM), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Fourier Transformed Infrared Spectrometry (FTIR) and Cation Exchange Capacity (CEC). The prepared zeolitic material were also applied in...
