“…With an increasing CS dosage from 0.1 to 0.5 g, a decrease in the uptake capacity from 22.2 to 4.49 mg/g for sunset yellow and from 29.4 to 5.78 mg/g for tartrazine was obtained. The decrease in the uptake capacity of CS for both anionic dyes with increasing CS dosage is ascribed to the decrease in the effective participation of the adsorption sites of CS as a result of aggregation/overlapping of the sites at higher doses (Mohammed et al 2019;Mondal 2017). Therefore, at lower CS doses there is a more efficient use of the active sites of CS resulting in higher dye loading.…”

The toxic effects of anionic dyes such as tartrazine and sunset yellow on humans and the aquatic environment are of serious concern. The need for the removal of these dyes from wastewaters led to the use of adsorption techniques as a cheap and efficient treatment method. Thus, this research was based on the preparation of a low-cost activated carbon derived from cassava sievate designated as CS, which was utilized in the adsorption of sunset yellow and tartrazine from simulated wastewater. The sorption process was carried out under varying process factors in a batch mode. Adsorbent characterization displayed the presence of surface functional groups by the FT-IR and a porous structure as revealed by scanning electron microscopy. Optimum dye uptake was recorded at pH (1.0–2.0), temperature (30–40 °C), CS dosage (0.1 g), and dye concentration (150 mg/L). A maximum CS monolayer uptake of 20.83 and 0.091 mg/g was recorded for tartrazine and sunset yellow dyes, respectively. The pseudo-second-order (R2 > 0.99) and Freundlich (R2 > 0.92) models were most fitted to the kinetics and isotherm data of the uptake of the dyes on CS. The adsorption equilibrium attainment was reached was within 90 min of dye sequestration. The experimental results revealed that both sunset yellow and tartrazine dyes were considerably adsorbed onto the environmentally compatible and low-cost activated carbon derived from cassava sievate.

“…The use of palm oil residues as adsorbents is of special interest as the palm oil agro-industry generates a significant amount of residual biomass (~87 million t/y) [14]. Several studies have demonstrated that biochar produced from palm oil and other agro-industrial residues is an effective adsorbent for removing heavy metals [15][16][17], dyes [18,19], pharmaceuticals [20][21][22][23], and other organic pollutants [24] from aqueous systems.…”

Evaluating the Removal of the Antibiotic Cephalexin from Aqueous Solutions Using an Adsorbent Obtained from Palm Oil Fiber

This study aimed to understand the adsorption process of cephalexin (CPX) from aqueous solution by a biochar produced from the fiber residue of palm oil. Scanning electron microscopy, Fourier transform infrared spectroscopy, Boehm titration, and the point of zero charge were used to characterize the morphology and surface functional groups of the adsorbent. Batch tests were carried out to evaluate the effects of the solution pH, temperature, and antibiotic structure. The adsorption behavior followed the Langmuir model and pseudo-second-order model with a maximum CPX adsorption capacity of 57.47 mg g−1. Tests on the thermodynamic behavior suggested that chemisorption occurs with an activation energy of 91.6 kJ mol−1 through a spontaneous endothermic process. Electrostatic interactions and hydrogen bonding represent the most likely adsorption mechanisms, although π–π interactions also appear to contribute. Finally, the CPX removal efficiency of the adsorbent was evaluated for synthetic matrices of municipal wastewater and urine. Promising results were obtained, indicating that this adsorbent can potentially be applied to purifying wastewater that contains trace antibiotics.

The traditional wastewater treatment plants are mostly not designed to deal with polar micropollutants such as pharmaceuticals. Therefore, antibiotics must be completely removed before their emission to ecosystems. Catalytic ozonation is used to increase the efficiency of sole ozonation further. In the present study, semi-batch experiments were conducted to investigate the efficiency of sole ozonation and catalytic ozonation in the degradation of oxy-tetracycline (OTC) as an environmental hazards contaminant in an aqueous solutions. Zinc oxide nanoparticles (ZnO) were used as a catalytic agent with ozone (ZnO/$${\mathrm{O}}_{3})$$ O 3 ) . The influence of operational parameters such as pH (3–11), initial oxy-tetracycline concentration (10–100) mg/l, temperature (15–35)°C, ozone generation rate (0.138–1.38)mg/s and catalyst dosage (25–200) mg/l on the ZnO/$${\mathrm{O}}_{3}$$ O 3 process was investigated. Ozone dosage was found to have the noticeable effect on the degradation process; however, the ZnO dosage was found to be less effective. The optimum condition was 1.38 mg/s at pH = 7, and after 35 min, a 94% of OTC removal was achieved. The results demonstrated that catalytic ozonation was a very effective method for degradation and mineralization of OTC in aqueous solution.
