Single and binary adsorption of sulfonamide antibiotics onto iron-modified clay: linear and nonlinear isotherms, kinetics, thermodynamics, and mechanistic studies

open access: yesApplied Water Science, 2018
Iron-modified raw kaolinite clay (Fe-MC) was synthesized by co-precipitation method, characterized, and then applied as a low-cost adsorbent to sequester sulfachloropyridazine (SCP) and sulfadimethoxine (SDM), emergent water contaminants, from aqueous ...

Evaluation of methodology for separation and identification of Tetraniliprole in maize (Zea mays) using RP-HPLC intended for residual analysis

open access: yesThe Indian Journal of Agricultural Sciences, 2020
The aim of this study was to develop and optimize an RP-HPLC technique for the residue determination of tetraniliprole and its metabolite (BCS-CQ 63359). Standardization was carried out by using simplified quick, easy, cheap, effective, rugged and safe (
