“…The activated carbon used in this study was produced from betel nuts. The highest component in the betel nuts was carbohydrate content of 60.86%, and the rest was water, protein, fat, and ash (Cundari et al, 2018a). Carbohydrates contained in the betel nuts forming a major component of the activated carbon in the amount of 86.27% based on the analysis of SEM-EDS (Cundari et al, 2018a).…”

One of the traditional arts in Indonesia is Jumputan fabric which produced by using tie and dye technic. The Jumputan wastewater contains organic compounds which can decrease the oxygen content in water. An economic and applicable process to handle the Jumputan wastewater is adsorption. The research was conducted to find out the effect of flowrate to the adsorption performance of the dye onto activated carbon in a continuous fixed-bed column based on the breakthrough curve parameter. The activated carbon made from betel nuts (Cyrtostachys lakka) with size particle of 60 mesh. The column dimension was 2 inches of inside diameter and 60 cm of height column. The bed height was 10 cm. The feed pumped from the top of column with variation of flowrate of 10, 20 and 30 ml/min. The absorbance of the dye was analyzed by using UV-Vis spectrophotometer. The adsorption column models were analyzed using Thomas, Yoon-Nelson, and Adam-Bohart. The result of this research was the dye removal efficiency decreased with the increase in flowrate, which was 61.4%; 56.9%; and 47.6% for 10, 20, and 30 ml/min respectively. Feed flowrate showed a negative effect on the saturation time, the higher the flowrate, the faster it reaches the saturation point of the adsorbent. The breakpoints were 180, 260, and 420 minutes at 30, 20, 10 ml/min flowrate. The model data indicated that Thomas and Yoon-Nelson are fitted well with the experimental results. The models show the largest regression and the smallest error with the value of each 0.99 and 0.0035 at flowrate of 10 ml/min.

This study aims to prepare activated carbon from an interesting biomaterial, corresponding to the cores of Ziziphus lotus, for the first time to the best of our knowledge, according to a manufacturing process based on its chemical and thermal activation. These cores were chemically activated by sulfuric acid for 24 h and then carbonized at 500°C for 2 hours. The obtained activated carbon was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and Brunauer–Emmett–Teller (BET) analysis. The adsorption of methylene blue (MB) on the activated carbon was evaluated, by Langmuir and Freundlich models examination, in order to explain the adsorption efficiency in a systematic and scientific way. Moreover, pseudo-first-order and pseudo-second-order kinetic models were used to identify the mechanisms of this adsorption process. The characterization results showed an important porosity (pore sizes ranging from 10 to 45 µm), a surface structure having acid groups and carboxylic functions, and a specific surface of 749.6 m2/g. Results of the MB adsorption showed that this process is very fast as more than 80% of MB is adsorbed during the first 20 minutes. In addition, increasing the contact time and temperature improves the MB removal process efficiency. Moreover, this adsorption’s kinetic modeling follows the pseudo-second-order model. Furthermore, data on the adsorption isotherm showed a maximum adsorption capacity of 14.493 mg/g and fit better with the Langmuir model. The thermodynamic parameters (∆G0, ∆S0, and ∆H0) indicate that the adsorption process is endothermic and spontaneous. Therefore, Ziziphus lotus can be used as a low-cost available material to prepare a high-quality activated carbon having a promising potential in the wastewater treatment.

Ziziphus lotus (Nbeg) is very common in Morocco where it occupies various ecosystems and presents different interests; however it remains devalued and knows recent deterioration due to the human pressure through clearing, wood collection, irrational cuts’ exploitation and overgrazing. This study aims to prepare activated carbon from the cores of this interesting biomaterial, for the first time to the best of our knowledge, according to a manufacturing process based on its chemical and thermal activation. The cores of Ziziphus lotus (Nbeg) were chemically activated by sulfuric acid (H2SO4, 98%) for 24h with a mass contribution (1:1), and then carbonized at a temperature of 500 °C for 2 hours. The obtained activated carbon was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy and specific surface measurement. These characterization results showed an important porosity and a surface structure having acid groups and carboxylic functions. The adsorption of methylene blue (MB) was evaluated, by Langmuir and Freundlich models examination, in order to explain the adsorption efficiency in a systematic and scientific way. Also pseudo-first order and pseudo-second order kinetic models were used to identify the possible mechanisms of this adsorption process. The results showed that the MB adsorption process on activated carbon follows the Langmuir model and that the adsorption kinetic is best represented by kinetics data of the pseudo-second order model. Therefore, Z. lotus can be used as a low-cost available material to prepare a high quality activated carbon having a promising potential in the wastewater treatment.
