Stem powder and its active carbon of plant for lead (II) removal: application to treat battery-based industrial effluents.

Stem powder and its active carbon plant are identified to have strong adsorptivity for lead ions. The bio-sorbents are characterized by conventional methods including XRD and FTIR analysis. These biomaterials are investigated for their maximum adsorption for lead ions by optimizing the extraction conditions.

Simultaneous removal of lead and cadmium ions from simulant and industrial waste water: using plant materials as sorbents.

The merit of this investigation is that simple and effective bio-sorbents based on plant materials with high sorption capacities, are developed for the simultaneous removal of the toxic Pb and Cd at neutral or nearly neutral pHs. These sorbents are successful in water remediation of Pb and Cd ions from real effluents from industries. These findings have great significance as the identified bio-sorbents are simple, effective and renewable in extracting highly toxic lead and cadmium ions from the effluents from industries or polluted water.

Synthesis of nanoZrO via simple new green routes and its effective application as adsorbent in phosphate remediation of water with or without immobilization in Al-alginate beads.

Nano particles of ZrO of average size 10.91 nm are successfully synthesized via green routes from a solvent blend of water and ethylene glycol (4:1 v/v). Bio-extract of seeds of Sapindus plant is employed as stabilizing and/or capping agent and homogeneous method of precipitation is adopted to generate the precipitating agent.
