Researchers from COMSATS Institute of Information Technology Report Findings in Chemical Engineering

May 28, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Current study results on Chemical Engineering have been published. According to news reporting from Islamabad, Pakistan, by VerticalNews journalists, research stated, "Mangifera indica biomass was chemically pretreated to evaluate its Ni(II) and Co(II) uptake capacity from aqueous solutions."

The news correspondents obtained a quote from the research from the COMSATS Institute of Information Technology, "The adsorption characteristics of Ni(II) and Co(II) by M. indica were found dependent on pH, chemical pretreatments, initial concentrations of the metals and time. The M. indica biomass was pretreated using HCl, HNO3, H3PO4, NaOH, CH3COOH, C6H6, HCHO and H2O2. The maximum Ni(II) and Co(II) uptake was 131.5 mg/g at pH 6 and 114.6 mg/g at pH 5, respectively at 30 C with NaOH pretreated M. indica biomass."

According to the news reporters, the research concluded: "The equilibrium adsorption data was better fitted to Langmuir adsorption isotherm model and pseudo-second order model."
