“…Table 2 is demonstrating the results obtained from the column. The breakthrough times of these curves decrease, and the curves dispersed and emerged slowly with increasing initial inlet concentration as demonstrated in Figure 4 at 20 mg/L concentration this effect was also observed by (Abdolali et al, 2017). Higher removal percentage was observed with the decrease of inlet concentration (Oguz et al, 2014).…”

The objective of this study is to examine the ability of a compost material for removing Cu 2+ from aqueous solutions with different parameters using continuous fixed-bed column. Compost was characterized by using Fourier transform infrared spectroscopy which revealed that the metal binding is mainly contributed to the ionic interaction of the metal cations with the carboxyl groups in the hemic substances. Scanning electron microscope images were utilized for morphological analysis of the adsorbent and has revealed that the changes in compost composition could be related to the mechanism of metal binding. Energy dispersive X-ray spectroscopy was used before and after the metal had loaded and gives a good evidence on compost adsorption of Cu 2+ and the metals have its involvement in the interaction in the adsorption process. The influence of the initial Cu 2+ concentration, flow rate, bed heights of the column, and ion exchange have been studied in this research. The adsorption kinetic models have revealed that the behaviour of the Cu 2+ adsorption is dependent on rate of concentration, flow rate, and bed heights.

BACKGROUND The alginate extraction residue from Brazilian Sargassum filipendula was employed as biosorbent for Zn(II) removal through a fixed‐bed column in order to explore its adsorptive properties and to establish a new use for this waste. RESULTS The best operating conditions were 0.5 mL min‐1 and 1.0 mmol L‐1 (inlet concentration), providing lower mass transfer zone and higher uptake. Elution percentages of 52 and 73% were obtained for the first and second desorption cycles, respectively, using CaCl2 as eluent. The Yan et al. model was more representative of the experimental data. Characterization revealed that ion exchange is involved between zinc ions and light metals (Ca, Na, K and Mg). A decrease was observed in real and apparent densities of biomass, with an increase in particle porosity of the residue after process. CONCLUSION The study revealed that this biomass has potential for Zn removal from aqueous solution, encouraging its application as a biosorbent in future studies involving multicomponent systems. © 2017 Society of Chemical Industry

The present work aimed to evaluate the effect of temperature, particle size and bed height of the chromium (VI) adsorption process using plantain peels in a continuous system. The experiment was carried out on a packed bed column, adjusting the feed temperature of the solution with a REX-C100 controller coupled to a type K thermocouple. The initial concentration of Cr (VI) was set at 100 ppm, the pH at 2 and the feed rate of 0.75 mL/s. The analyses were performed by UV-Vis spectroscopy using the colourimetric method of 1.5-diphenylcarbazide. The material was characterized by infrared spectrometry by Fourier Transforms (FTIR), from this analysis, it was determined that the OH and NH2 functional groups are the main responsible for the formation of complexes with the cations in solution. Also, it was established that only the particle size is statistically significant. According to the response surface analysis, the optimum conditions of the process were 353.15 K, a particle size of 0.819 mm and a bed height of 67.768 mm. From the thermodynamic study of the process, it is established that it is endothermic and the chemical adsorption prevails in it. The results obtained in the process modelling suggest that Dose-Response can be used reliably to scale the process.
