Abstract  We have implemented a single-stage procedure of preparing new biochar assisted manganese sulphide content to effectively extract hexavalent Chromium (Cr (VI)) and streamline the adsorbent sample preparation. The nanoscale MnS particles were extremely soldered on the supporting surfaces of biochar and were seen as a synergistic action among adsorbent and reduction and accumulation under … Continue reading Removal of chromium using biochar PRBs
