| Abstract | This study used dithizon (DZ) and mesoporous as a sorbent for simultaneous removal of heavy metal (mercury, cadmium and copper) ions from aqueous solution and real samples. Santa Barbara Amorphous synthesised and characterised by X-ray diffraction, Fourier-transform infrared spectroscopy and Brunauer–Emmett–Teller. Heavy metal ions measured by atomic absorption spectrometry and inductively coupled plasma optical emission spectrometry. Optimised conditions such as pH, removal time, sorbent dosage and concentration analyte with central composite design and obtained 5, 20 min, 20 mg and 25 ppm, respectively. The equilibrium data were fitted to isotherm models such as Langmuir, Freundlich and Tempkin and the results revealed the suitability of the Langmuir model. The maximum adsorption capacities for Hg2+, Cd2+ and Cu2+ ions achieved 25.04, 30.3 and 31.79 mg/g, respectively. Kinetics data fitting to pseudo-first order, pseudo-second-order and Elovich models confirmed the applicability of pseudo-second-order kinetic model for the description of the mechanism and adsorption rate. This sorbent could regenerate easily with ethylenediamminetetraacetate solution. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
