Dynamic Cr(III) uptake by Macrocystis pyrifera and Undaria pinnatifida biomasses

Plaza Cazón, Josefina; Viera, Marisa; Donati, Edgardo.
Electron. j. biotechnol; 16 (3), 2013
Background: The increased industrial activity has resulted in the discharge of large amount of pollutants including non-degradable metals into the environment. Chromium is produced in several industrial processes and it can be found in the environment in two stable oxidation states, Cr(VI) and Cr(III). C...

Biosorption of hexavalent chromium using tamarind (Tamarindus indica) fruit shell-a comparative study

Rao Popuri, Srinivasa; Jammala, Ajithapriya; Naga Suresh Reddy, Kachireddy Venkata; Abburi, Krishnaiah.
Electron. j. biotechnol; 10 (3), 2007
The adsorption of chromium (VI) ions from aqueous solutions has been investigated on crude tamarind fruit shell, HCl treated and Oxalic acid treated shells at room temperatures. The biosorbents are characterized by FT-IR, EDXRF and porosimetry. The biosorption experiments are conducted through batch syst...
