Abstract:
The capacity of metal sludge in removing reactive dyes was investigated using RR-2, RR-120 and RR-141, increasing in number of sulfonic groups. Batch adsorption with 2 g/l of metal sludge (<75 pm) showed that SO%, 90% and 98% of RR-2, RR-120 and RR-141, respectively, was removed &om 30 mg/l dye solutions within 50 minutes without pH adjustment. The optimum system pH is 8-9, close to pHzp,, and maintained in the initial solution pH 3- 10. The adsorption capacities, following the Langmuir model, were 48-62 mg dyelg adsorbent. The thermodynamic and desorption results elucidate that adsorption of RR-2 was physical but that of RR-120 and RR-141 was mainly chemical. The mechanism involved ion exchange between OK and SOs-, but dye-metal complexes are formed at system pH 2. The larger particles yield the lower adsorption rate, solved by increasing contact time or amount of adsorbent. The treated water was nontoxic in the system pH above 5 or initial pH above 2. The particles of 150-300 ym were optimal for column adsorption using EBCT above 5 minutes, bed depth-to-diameter ratio 3-6, and minimum usage rate 1.3 g/l. The column capacity for RR-141, following the BDST model, was 29.39 mg dyelg adsorbent. Adsorption by 10 g/l of metal sludge can be economically applied to remove color, COD and SS from real wastewater with optimum pH and free of toxic heavy metals. Metal sludge from various sources can be applied because ferric hydroxide has a significant role in the adsorption, which is enhanced by other heavy metals.
