Autor: Trilochan Prasad Sahoo, Subrata Dasgupta, Mahesh Kumar Gagrai, Mrinal Kanti Dolai, Moumita Debroy

Publikováno v: Groundwater for Sustainable Development. 12:100512

This study aims to investigate the sorption behavior of As(III) in presence of fluoride ion in an aqueous solution. Conventionally the As(III) is removed by converting it to As(V) with certain oxidants followed by sorption or precipitation. Limited i

Non-ideal metal binding model for Cr(III) sorption usingSpirulina platensisbiomass: Experimental and theoretical approach

Autor: Mahesh Kumar Gagrai, Animes Kumar Golder, Chandan Das

Publikováno v: The Canadian Journal of Chemical Engineering. 91:1904-1912

Removal of Cr(III) from aqueous solution using Spirulina biomass was studied in a batch experiment. Spirulina biomass was characterised before and after Cr(III) sorption using FTIR, SEM and potentiometric titration. The effects of experimental parame

Reduction of Cr(VI) into Cr(III) by Spirulina dead biomass in aqueous solution: kinetic studies

Autor: Chandan Das, Mahesh Kumar Gagrai, Animes Kumar Golder

Publikováno v: Chemosphere. 93(7)

Microalga species are potential scavengers of heavy metals. The active functional groups of a number of biomaterials are capable to detoxify Cr(VI) to Cr(III). A 2nd order kinetic model was developed in terms of concentration of protonated acidic gro

Biological reduction and removal of Cr(VI) with microbial consortia collected from local water treatment plant

Autor: Chandan Das, Animes Kumar Golder, Mahesh Kumar Gagrai

Publikováno v: International Journal of Environmental Technology and Management. 17:508

Application of microbes in water treatment is a well-established technique. A few microbes are tolerant to toxic heavy metals. Cr(VI) tolerant microbes have practical importance of detoxifying Cr(VI) to Cr(III). The water treatment plant situated at
