In the present study, the novel organic ligand of N,N–bis(salicylidene)1,2–bis(2–aminophenylthio)ethane based optical sensor material was fabricated by direct immobilization approach. The resultant sensor material was maintained with a high surface area with ordered mesoporosity even after successfu...

The contamination of natural resources by hexavalent chromium (Cr(VI)) originating from natural and anthropogenic activities is a serious environmental concern. Although many articles on chromium remediation have been published, a comprehensive understanding of the mechanisms involved in remediation...

Chromium (VI) is an important heavy metal commonly found in tannery wastewater. In order to manage this type of environmental pollution, there needs to be a better understanding of Cr(VI) adsorption mechanisms. This article reviews the recent usage of various adsorbents to adsorb Cr(VI) from wastewa...

Carbamazepine (CBZ) is a typical pharmaceutical residue commonly found in aqueous environments, but its removal through activated carbon or advanced oxidation processes is often disrupted by co-existing organic matter. An imprinting system which consisted of the target pollutant CBZ (template molecu...

Over the last decade, direct analysis in real time (DART) has emerged as a viable method for fast, easy, and reliable "ambient ionization" for forensic analysis. The ability of DART to generate ions from chemicals that might be present at the scene of a criminal activity, whether they are in the gas...

Three different types of activated carbon were synthesized from tea-waste by chemical activation method using three activating agents - H3PO4 (H-AC), KOH (K-AC) and ZnCl2 (Z-AC) for analyzing the influence of activating agents on the physicochemical and adsorptive properties of materials. Energy dis...

Chitosan and poly(1-vinylimidazole) are both potential adsorbents to remove Cr(VI). Here, we designed the preparation of new adsorbents by combining chitosan and poly(1-vinylimidazole) to get the synergistic effect for the removal of hexavalent chromium. Trimethoxysilyl group terminated poly(1-vinyl...

Stir-bar sorptive extraction (SBSE) is a popular solvent-less sample preparation method, which is widely applied for the sampling and preconcentration of a wide range of non-polar solutes. A typical stir-bar for SBSE is composed of a polydimethylsiloxane (PDMS) film, coated onto a glass jacket with ...
