Chitosan biopolymer was converted to thiourea-chitosan followed by impregnation with ionic liquid Aliquat-336 using microwave irradiation method. The obtained material Ionic Liquid-Thiourea Chitosan (ILTC) was effectively used for decontamination of Cd(II) and Hg(II) from water bodies. FT-IR, SEM-EDX, XRD and TGA-DTA gives insight of ILTC adsorbent. Choro-complexes of Cd(II) and Hg(II) showed strong adsorption on ILTC as compared native Cd(II) and Hg(II) ions hence the adsorption was carried out in the form of chloro complexes. The adsorption behavior of Cd (II) and Hg (II) ions onto ILTC was investigated through batch method and various batch parameters viz. Contact time, adsorbent dose, initial concentration of adsorbate, pH and point of zero charge were optimized. The maximum adsorption capacities for Cd (II) and Hg (II) at 298 K were found to be 442.5 mg/g and 203.2 mg/g resp. at pH 3.0. Kinetic and thermodn. parameters of the adsorption process were obtained. The results indicated that adsorption process was spontaneous, exothermic and followed pseudo-second-order kinetics model. Column studies were carried out in order to access the applicability of the material for bulk samples at larger volumes ILTC could be easily regenerated and efficiently reused. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Product Details of 5137-55-3).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. 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.Product Details of 5137-55-3
