Over the past few decades an increasing array of molecular-level analytical probes has provided new detailed insight into mineral and radionuclide interfacial reactivity in subsurface environments. This capability has not only helped change the way mineral surface reactivity is studied but also how fieldscale contaminant migration problems are addressed and ultimately resolved. Here we review r...

In the hydrometallurgical processing of complex ores/ concentrates/ secondaries/ wastes, the solutions containing different non-ferrous metals are obtained during teaching the materials in acidic, ammoniacal or alkaline lixiviants. The spent solutions and effluents are also generated in different process industries and contain metallic values. Their discharge in the sewage or river is major con...

Biological processes, such as activated sludge and granular sludge are widely used to remove organic pollutants as well as inorganic pollutants, such as metallic elements1–3, which are known to be potentially toxic, and impact the performance of biological waste treatment processes4. Granular sludge is a dense aggregate of microorganisms, minerals, and microbial produced compounds such as extra...

Phthalates are common plasticizers used in pPVC (plasticized polyvinyl chloride) products. Phthalates are commonly found in the child rearing products (for teething, toys etc.), blood bags, dialysis tubing, paints, lacquers, cosmetics, coatings of capsules etc. The present study was conducted to explore the potential of new microbial strains for the biodegradation and biotransformation of phtha...
