The effect of zero-valent iron nanoparticles (nZVI) addition on methane production during anaerobic digestion pig slurry was assessed. Experiments were conducted using two experimental set-ups: batch and long-term continuous operation at a fixed nZVI dosage. Two different temperature ranges (mesophilic thermophilic) Biogas content monitored, the specific methanogenic activity biomass oxidation ...

S. Ponmani and C. Udayasoorian Abstract -A new class of nano scale zero valent iron (nZVI) particles supported on activated carbon (AC) were synthesized and the feasibility of using nanocomposite (AC+nZVI) for the removal of Cr(VI) in water was investigated through laboratory batch test. Nanocomposite was synthesized by impregnating carbon with ferrous sulfate followed by chemical reduction wit...

Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...

The chromium pollution of water is an important environmental and health issue. Cr(VI) removal by means of metallic iron is an attractive method. Specifically, nanoscopic zero valent iron (NZVI) shows great reactivity, however, its applicability needs to be further investigated. In the present paper, NZVI was supported on MgO grains to facilitate the treatments for remediation of chromium-conta...

Inorganic Nanoparticle Luminophores have been the focus of ongoing research because their special characteristics as they approach nanoscale from bulk nature. Besides, application remains highly diverse compared to zero-valent metals. In this work, facile and economical borohydride reduction ferric chloride was undertaken study kinetics phenol photodegradation under simulated sunlight condition...
