Nickel (II) removal using modified Citrus limettioides peel

Equilibrium and kinetic studies on Ni(II) removal from aqueous solution by Citrus Limettioides peel and its carbon adsorbent

Activated carbon has been prepared from Citrus limettioides peel (CLPC); a novel waste material by chemical modification with sulphuric acid followed by bicarbonate treatment applied for the adsorption of Ni(II) from aqueous solutions. Batch experiments have been carried out to study the effect of various parameters such as contact time, pH and adsorbent dosage on various Ni(II) concentrations ...

Citrus Peel Gasification using Molten Sodium Heat Pipes

Extraction of Citrus Flavonoids from Peel of Citrus Junos Using Supercritical Carbon Dioxide with Polar Solvent

Abstract Citrus juice processing residues are mainly composed of peel, juice sack and seed. The peel, especially, consists of bioactive compounds such as flavones. Supercritical carbon dioxide (SC-CO2) extraction of flavonoid was carried out at a pressure of 30 MPa and temperature ranging from 80 to 160°C. Ratio of water and ethanol as a co-solvent was varied from 0 to 100%. Flavonoids such as ...

Microbial production of pectin from citrus peel.

A new method for the production of pectin from citrus peel was developed. For this purpose, a microorganism which produces a protopectin-solubilizing enzyme was isolated and identified as a variety of Trichosporon penicillatum. The most suitable conditions for the pectin production were determined as follows. Citrus (Citrus unshiu) peel was suspended in water (1:2, wt/vol), the organism was add...

Antibacterial activity of Citrus reticulata peel extracts.

Citrus peels were successively extracted with hexane, chloroform and acetone using a soxhlet extractor. The hexane and chloroform extracts were fractionated into alcohol-soluble and alcohol-insoluble fractions. These fractions were tested against different gram positive and gram negative bacteria. The EtOH-soluble fraction was found to be most effective. Fractionation of EtOH-soluble fraction o...
