Pharmaceutical industry uses activated carbon
as an antidote to poison caused by toxins ingestion.
The Philippines, to note, has been exporting activated carbon
for over five decades already, according to industry sources.
Commercial activated carbon
and (K2Cr2O7) were purchased from Merck.
Calgon Carbon is the world's largest producer of granular activated carbon
and supplies more than 100 types of activated carbon
products in granular, powdered, pelletized and cloth form for more than 700 distinct applications.
The activated carbon
was completely burned, and the rest was Zn[Fe.sub.2][O.sub.4].
After adsorption tests the type of model that better set to the data was determined, in order to have a closer idea about amounts of contaminant adsorbed by the activated carbon
in each of the tests, this was done relying on rigorous mathematical analysis of the data taken along experiments.
Acid-washed and catalytic activated carbons
are also available for applications where purification levels achievable by standard activated carbons
are insufficient.Acid-washed activated carbons
are used in ultra-pure environments due to their exceptional purity and catalytic activated carbons
provide improved performance for the removal of chloramines and hydrogen sulphide from water, as well as to standard the adsorptive characteristics of regular activated carbon
is applied widely in a variety of fields such as food and chemical industries, wastewater treatment, solvent recovery, air pollution control and hyrometallurgy for the recovery of gold and silver .
In the present work, this research is extended to activated carbon
Chitosan was supplied by Shanghai Lanji Science and Technology company (degree of deacetylation) > 90%; activated carbon
was supplied by Liyang Zhuxi Activated Carbon
company; span 80 was supplied by Sinopharm Chemical Reagent Co., Ltd.; acetic acid, liquid paraffin, formaldehyde, NaOH, epichlorohydrin, ethanol, and methyl orange are all analytically pure.
It was allowed to cool and washed with distilled water until a neutral pH was obtained, oven-dried at 100[degrees]C for 12hrs, and then kept in air tight pack for further analysis and labelled as CPZAC (carbonized plantain zinc chloride activated carbon
), CPPAC (carbonized plantain phosphoric acid activated carbon
), and UPC (untreated plantain carbon).
