Colored compounds adsorption from the textile dyeing effluents on activated carbons produced from various
indigenous vegetable sources by zinc chloride activation is studied. The most important parameters in chemical activation were found
to be the chemical ratio of ZnCl2 to feed (3:1), carbonization temperature (460�470 캜) and time of activation (75 min). The
absorbance at 511 nm (red effluent) and 615 nm (blue effluent) are used for estimation of color. It is established that at optimum
temperature (50 캜), time of contact (30�40 min) and adsorbent loading (2 g/L), activated carbons developed from rain tree (Samanea
saman) saw dust and blackberry (Randia formosa) tree saw dust showed great capability to remove color materials from the effluents.
It is observed that adsorption of reactive dyes by all types of activated carbons is more than that of disperse dyes. It is explained
that because of its acidic nature the activated carbon can adsorb better reactive dye particles containing large number of nitrogen
sites and 뻊O3Na group in their structure. The use of activated carbons from the indigenous biomass would be economical, because
saw dusts are readily available waste worldwide. |
