In this study, the toxic cationic dye of methylene blue (MB) was encapsulated by the polymeric natural carbohydrate of turmeric powder (TP) adsorbent. The natural TP adsorbent was characterized to define the functional groups existing for complexation ability to the MB dye molecules. The MB dye adso...

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 h...
