Abstract:
The work's aim is the development of a sustainability goal for waste-water treatment by adsorbing and removing chromium (VI)) ions using algal biochar. The algal biochar is synthesized in a tube furnace using a process of slow Pyrolysis at 500°C for 60 min. In the present study batch experiment is performed with different concentrations of Chromium (VI)(1,10,25,50,100ppm) at different time (15,30,60,120,240 min) to evaluate the removal efficacy. The reagent with 1,5 diphenyl carbazide is used as a reagent for the determination of chromium (VI) and analyzed at 500 nm using a UV -Vis spectrophotometer. The adsorption mechanism was assessed using the linear Langmuir and Freundlich model and evaluated which model is best fitted for the removal of Chromium VI. The Langmuir model fitted the experimental data, with a maximum adsorption capacity of 54.94505 mg/g. The best kinetic fit was found with the pseudo-second-order. The maximum removal percentage of chromium (VI) is 97.8428% obtained at pH 4 and metal concentration of 1ppm. The results obtained are useful for future works by using algal biochar as an adsorbent of Cr (VI) from the textile waste water to attain sustainability development goal.
