In the present study, novel ionic liquid-impregnated chitosan hydrogel beads (CS-TCMA) were fabricated via the reaction of tricaprylmethylammonium chloride (TCMA, Aliquat-336) with the chitosan’s amino groups. They were used for the fast adsorption of Tetracycline (TC), as a pharmaceutical compound model, from aqueous solution It was found that the impregnation of TCMA greatly improved the adsorption behavior of chitosan toward TC. The optimum adsorbent was determined to be 3 mg/ L in a wide pH range of 5-11. It was a fast process, with a 90% removal efficiency in <45 min. The adsorption kinetic of TC on the CS-TCMA was well described by the pseudo-first-order model and intra-particle diffusion model. The adsorption also obeyed the Langmuir adsorption isotherm model and the maximum adsorption capacity obtained was 22.42 mg/g at 45°C. The thermodn. study also revealed the endothermic nature of the process. The adsorption mechanism was also studied. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Electric Literature of C25H54ClN).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Electric Literature of C25H54ClN
