https://www.jspae.com/index.php/jce <p><strong>Journal of Chemistry and Environment (ISSN: 2959-0132) </strong>is a peer-reviewed, open access international journal that publishes original research and reviews in the fields of chemistry and protecting our environment for the future in an ongoing way. Our central goal is to provide a hub for researchers working across all subjects to present their discoveries and to be a forum for the discussion of important issues in the field. All scales of studies and analysis, from impactful fundamental advances in chemistry to interdisciplinary research across physical chemistry, organic chemistry, inorganic chemistry, biochemistry, chemical engineering, and environmental chemistry disciplines, are welcomed. All manuscripts must be prepared in English and are subject to a rigorous and fair peer-review process. Accepted papers will appear online within 3 weeks, followed by printed hard copies.</p> en-US jceeditorial@gmail.com (Asad Ali) jceeditorial@gmail.com (Asad Ali) Fri, 15 Dec 2023 00:00:00 +0000 OJS 3.3.0.12 http://blogs.law.harvard.edu/tech/rss 60 https://www.jspae.com/index.php/jce/article/view/146 <p>Unprocessed waste is dumped in lakes and rivers which possess a severe environmental risk through heavy metal’s contamination within the food chain, especially chromium Cr⁶⁺. It applies for sustainable development goals by using green solid waste as a precursor. This research mainly focuses upon the analysis of time effect for Cr⁶⁺ removal by FeCl₃ modified biochar using sugarcane bagasse and peanut shell powder as biomass. Adsorbent preparation was done using Bench-Scale Fixed Bed Reactor (B-SFBR) and Cr⁶⁺ was found using the calorimetric method. Characterization was done by BET, SEM-EDX, and FTIR. The highest Cr⁶⁺ percentage removal was achieved by Modified Peanut shell Powder with 99.97% removal upon pH 2, shaking time 180 mints, speed = 150 rpm, dosage 0.3 g, Cr⁶⁺ conc 20 mg/L. Percentage Removal by Modified SB was 98.96% with Cr⁶⁺ conc 20 mg/L, dosage 0.3 g, pH 2, shaking speed 150 rpm, time 180 mints. Hence, the present experimental research concludes that FeCl₃ modified peanut shell powder shows greater Cr⁶⁺ removal efficiency up to 99.97 %.</p> Syeda Hijab Zehra; Said Akbar Khan; Syeda Mahnoor Zehra, Muhammad Zeeshan Asad Copyright (c) 2023 https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.jspae.com/index.php/jce/article/view/146 Thu, 06 Jul 2023 00:00:00 +0000
