Insight into the chemically modified crop straw adsorbents for the enhanced removal of water contaminants: A review
(
Elsevier B.V.
, 2021 , Article Review)
Crop straws represent the major part of lignocellulosic wastes that mainly consist of three polymeric components, namely cellulose, hemicellulose, and lignin. These straws gain great attention owing to their low cost, ...
Nonenzymatic Electrochemical Sensor Based on CuO-MgO Composite for Dopamine Detection
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Dopamine plays an essential role in the proper functioning of the brain and the body. A change in the level of dopamine can lead to disorders related to the nervous system. Thus, detection of dopamine levels may aid in the ...
Desorption of chloramphenicol from ordered mesoporous carbon-alginate beads: Effects of operating parameters, and isotherm, kinetics, and regeneration studies
(
Elsevier Ltd
, 2021 , Article)
This study has investigated the desorption of an emerging contaminant, known as chloramphenicol (CPC), from ordered mesoporous carbon (OMC)-alginate beads. The effects of initial concentration, operating temperature, and ...
Lithium loaded coal fly ash as sustainable and effective catalyst for the synthesis of glycerol carbonate from glycerol
(
Elsevier Ltd
, 2021 , Article)
Coal fly ash (CFA) has been employed as a catalytic support for lithium ions by impregnation. The basicity, basic strength, and stability of the resultant catalyst were further tuned by varying active species concentration ...
