Magnetic nanomaterials for the removal, separation and preconcentration of organic and inorganic pollutants at trace levels and their practical applications: A review

Matrix-dispersed magnetic molecularly-imprinted polyaniline for the effective removal of chlorpyrifos pesticide from contaminated water

“…20 Recently, the attention of many researchers has been grasped by the use of magnetic nanomaterials for the removal of hazardous contaminants, including pesticides, from water. [21][22][23][24] The removal of CPF from water via bioremediation, [25][26][27][28] Fenton reaction, [29][30][31][32][33] graphitic carbon nitride-incorporated chitosan 34 and metal nanoparticles 35 was reported in the literature. CPFselective MIPs and magnetic MIPs (MMIPs) were also reported using different kinds of polymers either for extraction/preconcentration or removal of CPF.…”

Extraction Techniques used for the Removal of Pharmaceuticals from Environmental Samples

“…Extraction, on the other hand, is often relegated to a supporting function, and it has only been in the last 15 years or so that the relevance of extraction technology has been acknowledged for its role in the development of highquality analytical data. [6][7][8][9] Extraction operations are often classified as "pre-treatment. " That is, extraction serves to separate analytes from potentially interfering reaction mixture while also preparing these analytes for assessment.…”

Recent Developments in Chitosan-Based Adsorbents for the Removal of Pollutants from Aqueous Environments

“…Dyes, phenolic compounds, metallic ions and micropollutants, such as pesticides and drugs, have all been detected in wastewaters, surface and even drinking water, indicating that the conventional methods used in treatment plants are not optimised for their removal [ 4 ]. Consequently, the removal of these pollutants with high toxicity, even when present at low concentrations, has been increasingly studied in the scientific world [ 5 , 6 ].…”
