Dynamic isotherms of dye in activated carbon

Abstract: Textile industrial wastewaters have significant quantities of dyes. Adsorption processes using industrials rejects may help in the treatment of these effluents. In this context, uptake of Reactive Blue 5G dye by babassu coconut shell activated carbon was studied with upstream flow fixed-bed experiments. First, the minimum flow rate that minimizes the diffusion effects of 4 mL/min was chosen within the range investigated (2-10 mL/min). Then, the breakthrough curves were obtained for this flow rate for different… Show more

“…Activated carbon adsorption processes are often used for this purpose due to their versatility, efficiency and low operating costs (Matta et al, 2008;Lambrecht et al, 2007). Owing to its structural characteristics, specifically its large surface area and high pore distribution, activated carbon is a highly efficient adsorbent (Bangash and Alam, 2009).…”

“…Based on the results, wasted black tea is rich in elements such as carbon and calcium similar to the activated carbon. The high concentrations of these elements allow the adsorbent to exhibit high sorption capacity [28].…”
