The magnetic and non-magnetic layered double hydroxide (LDH@Fe3O4 and LDH) were developed via simple co-precipitation method. After modified by methyltrioctylammonium chloride (N8881Cl), the absorption capability of the materials for inorganic pollutant perchlorate (ClO–4) improved obviously through ion exchange. Then the characteristics of studied materials were examined by SEM (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform IR spectroscopy (FT-IR), X-ray photoelectronic spectroscopy (XPS) and Zeta potential measurements. The removal performance of ClO–4 from water was investigated, and the effects of adsorption parameters on the efficiency were studied, such as contact time, initial concentration, pH and co-existing anions. The adsorption process was quite rapid and the removal rate could reach over 90% on N8881Cl-LDH@Fe3O4 within just 1 min. Maximum adsorption capacities were observed as 50.58 and 60.68 mg g-1 for N8881Cl-LDH and N8881Cl-LDH@Fe3O4 at 303 K. Moreover, the pH and common co-existing anions had little effects on adsorption capacity of ClO–4. It was found that the equilibrium adsorption process could be well described by pseudo-second-order kinetic model and Langmuir adsorption isotherm model. In brief, the N8881Cl-LDH@Fe3O4 synthesized in this study has the characters of low cost, mild conditions and easy operation, showing satisfactory absorption performance such as fast adsorption and low pH-dependence, which is potential on ClO–4 removal from aqueous solution 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 are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Product Details of 5137-55-3
