Optimization of an innovative composited material for effective monitoring and removal of cobalt(II) from wastewater

A newly designed composite adsorbent (CpAD), ultra-trace detection ability and a superior adsorption capability to that novel material, was fabricated by functional ligand (3-(((5-ethoxybenzenethiol)imino)methyl)–salicylic acid) combining with mesoporous silica. The resultant CpAD was maintained a high surface area with ordered porosity even after successful ligand anchoring. The application of cobalt (Co(II)) detection and adsorption was measured at an optimum experimental protocol with exhibition of significant color visualization. The experiment conditions were optimized based on contact time, solution pH, initial Co(II) concentration and diverse competing metal ions. The CpAD was able to detect the low level Co(II) ion as the detection limit was 0.39 μg/L. The data were clarified that the CpAD was not affected with the existing competing ions and…
