Comparison Between Some Common Clays as Adsorbents of Carotenoids, Chlorophyll and Phenolic Compounds from Vegetable Oils
Adsorbents of Carotenoids Chlorophyll and Phenolic Compounds
2016/6/2
Four different clays were compared for their capacities to adsorb chlorophyll and carotenoids; two major pigments in vegetable oils at 30 and 100°C. The clays used include Fulmont, Tonsil N, Tonsil AC...
Cr(VI) Ions Removal from Aqueous Solutions Using Natural Adsorbents – FTIR Studies
FTIR Chromium (VI) Rice Straw Hyacinth Roots Saw Dust
2013/3/12
The ability of eight natural adsorbents were investigated for adsorptive removal of Cr(VI) from aqueous solutions. Various physico-chemical parameters such as pH, initial metal ion concentration, adso...
