dc.description.abstractThe present study was undertaken forremovel of chlorpyrifos pesticide from water by using solvothermally synthesized Metal Organic Framework, HKUST-1 was synthesized taking high boiling solvent DMF and Trimesic acid as the organic linker. Successful characterization was done by different techniques i.e., Fourier transform infrared spectroscopy (FTIR), particle size analyzer (PSA), X-ray diffraction (XRD) and field emission scanning microscopy (FESEM). FTIR studies showed that HKUST-1 have bonding between metal and organic linker, vibrations between the BTC bonds, PSA showed the range of particles was from 4900 nm to 5300 nm, XRD showed crystallanity of the MOF, FESEM showed the particle size between 5 μm to 13 μm. Reults showed that the removal efficiency of HKUST-1 was 76% at the optimized conditions of pH, amount of HKUST-1, contact time, temperature and concentration. The maximum adsorption capacity were found as 98 mg/g for linear and 102 mg/g for non linear. The study of adsorption isotherms and kinetic modelling were also done. Langmuir adsorption isotherm and pseudo second order fitted best and are the deriving force of chemisorption. Reuseablity results showed that the removal efficiency decrease from 3 to 5% by washing the adsorbent with solvent. The responsible interaction for adsorption was electrostatic interaction, it can be concluded from the present study that HKUST-1 is a highly efficient MOF for the removal of chlorpyrifos.en_US
