    Green chemistry approach for synthesis of environmentally sustainable advanced polymeric nanoparticles

    By Mansi Tiwari, Susarla Venkata Ananta Rama Sastry, Sandeep Kumar

    Abstract: The distinctive properties of the Advanced Polymeric nanoparticles (PNPs) have gained substantial attention in several arenas. However, conventional nanoparticle synthesis methods often involve the use of hazardous solvents and energy-intensive processes, which can contribute to environmental concerns. To address these challenges, progressive techniques have emerged, aiming to prepare advanced polymeric nanoparticles in an environmentally sustainable manner for green chemistry applications. Each technique is analyzed in terms of its potential to …

    Predicting Rate Equation for the Synthesis of Octadec-9-Enoic Acid Methyl Esters by the Methanolysis of Pongamia Pinnata Triglycerides Using Sono Reactor

    By Susarla Venkata Ananta Rama Sastry

    Abstract: In the present work, octadec-9-enoic acid methyl esters are synthesized from pongamia pinnata oil using methanolysis in sono reactor. The rate equation is predicted for the methanolysis reaction. The produced methyl esters from pongamia pinnata oil confirmed to ASTM D6751 standards. Fourier Transform Infrared Analysis and Gas Chromatography Mass Spectrometry were used to characterise the methyl esters. The rate is dependent greatly on methanol concentration, and then on catalyst concentration …

    Chemical and Electrocoagulation for Chromium (VI) Removal from Galvanic Effluents

    By Susarla Venkata Ananta Rama Sastry

    Abstract: Industrial effluents usually contain 10 to 500 mg/l Cr(VI); that according to internationalenvironmental rules must be set at permissible levels before being discharged into the environment.The upper permitted levels of chromium are 0.5 mg/l for effluent discharge and 0.01 mg/l for drinkingwater respectively. Hexavalent chromium is a very toxic heavy metal moiety occurring in variousindustrial wastewaters, such as electroplating, anodizing, tanning and dyeing effluents. Industrialeffluents may contain hundreds of mg/l …
