Bioremediation of Ni(II) and Cu(II) from wastewater by the nonliving biomass of Brevundimonas vesicularis

  The nonliving biomass of Brevundimonas vesicularis was used for the biosorption of nickel and copper from their single and binary solutions after its pretreatment with 0.1 N NaOH. The optimum conditions, such as pH, initial metal ion concentration, contact time and biomass dose were determined experimentally. From the linear plot of Langmuir isotherm model, maximum absorption capacities (qmax) of...

Kinetics of proton depended oxidation of diethylthiourea with methylene green in aqueous medium

  Diethylthiourea (DETU) reacts with methylene green (MG) and reduced it into leuco dye where it oxidized into smaller fragments like urea, nitrate and sulphate. The reaction was favorable in acidic condition. A direct relation in between oxidation of DETU and MG to the concentration of H+ ions was observed through typical kinetics in two acids like HCl and H2SO4. The second order with respect to HCl and...
