The biosorption process for the removal of nickel(II) by loofa sponge-immobilized biomass of Chlorella sorokiniana (LIBCS), a newly developed immobilized biosorbent, was characterized. Effects of environmental factors on metal uptake capacity of LIBCS were studied and compared with free biomass of C. sorokiniana (FBCS). Nickel(II) removal by LIBCS was found(More)
AIMS The aim was to develop a new, efficient and cost-effective biosorbent for the removal of heavy metals from aqueous solution. METHODS AND RESULTS A new biosorbent was developed by immobilizing a unicellular green microalga Chlorella sorokiniana within luffa sponge discs and used for the removal of metal ions from aqueous solution. Microalgal-luffa(More)
In this work, [Emim]Gly ionic liquid was used for the pretreatment of bamboo biomass followed by regeneration of cellulose-rich material. Thermal degradation study of untreated bamboo and cellulose-rich material was carried out under dynamic condition using thermogravimetric analysis. Free kinetics models of Kissinger, Ozawa, Flynn–Wall–Ozawa, and(More)
A simple, sensitive and selective solid phase reflectometry method is proposed for the determination of trace mercury in aqueous samples. The complexation reagent dithizone was firstly injected into the properly buffered solution with vigorous stirring, which started a simultaneous formation of nanoparticles suspension of dithizone and its complexation(More)
A micro near infrared spectroscopy (MicroNIRS) technique based on monolithic column enrichment has been developed to detect low concentration metallic ions in water. Glycidyl methacrylate-ethylene dimethacrylate-iminodiacetic acid (GMA-EDMA-IDA) monolithic material was synthesized to construct an enrichment device, which can enrich metallic ions more(More)
An ultrasensitive method based on Surface enhanced Raman scattering (SERS) has been developed to determine content of a pesticide which is tricyclazole in paddy rice using sliver colloid as a substrate and pyridine as an internal standard. The peaks at 424 and 1035 cm(-1) in a SERS spectrum were selected as analytic and internal peaks, respectively, and(More)
Groundwater pollution due to anthropogenic activities is one of the major environmental problems in urban and industrial areas. The present study demonstrates the integrated approach with GIS and DRASTIC model to derive a groundwater vulnerability to pollution map. The model considers the seven hydrogeological factors [Depth to water table (D), net recharge(More)
Sensitive detection of heavy metal ions in water is of great importance considering the effects that heavy metals have on public health. A developed fluidized bed enrichment technique was used to concentrate and detect low concentrations of Cu2+, Co2+, and Ni2+ in water samples by near-IR diffuse reflectance (NIDR) spectroscopy (NIDRS) directly without(More)
