This study was carried out to treat the aqueous solutions containing reactive dyes(RB19, RR120 and
RY179) by the Ozone demand flask method and adsorption process using activated carbon fiber(ACF) which are
one of the main pollutants in dye wastewater. Ozone oxidation of three kinds of the reactive dyes was examined
to investigate the reactivity of dyes with ozone, competition reaction and ozone utilization on various conditions
for single- and multi-solute dye solution. Concentration of dyes was decreased continuously with increasing
ozone dosage in the single-solute dye solutions. Competition quotient values were calculated to investigate the
preferential oxidation of individual dyes in multi-solute dye solutions. Competition quotients(CQi) and values of
the overall utilization efficiency, ηO3, were increased at 40mg/l of ozone dosage in multi-solute dye solutions.
ACF(A-15) has much larger specific surface area(1,584㎡/g-ACF) in comparison with granular activated carbon
adsorbent (F400, 1,125㎡/g-GAC), which is commonly used, and most of pores were found to be micropores with
pore radius of 2nm and below. It was found that RB19 was most easily adsorbed among the dyes in this study.
In the case of PCP (p-chlorophenol) and sucrose, which are single component adsorbate, adsorption capacities of
ACF(A-15) were in good agreement with the batch adsorption measurement, and saturation time predicted of
ACF columns for these components was also well agreed with practically measured time. But in the case of
reactive dyes, which have relatively high molecular weight and aggregated with multi-components, adsorption
capacities or saturation time predicted were not agreed with practically measured values. |
