“…Adsorption is preferable for antibiotic-loaded wastewater treatment due to its low-initial effectuation costs, easy operation, and high adsorption effectiveness of CECs from wastewaters (Caicedo et al, 2020;dos Reis et al, 2016;Thue et al, 2020;Tomul et al, 2020, Yazidi et al, 2020.…”

Two carbon composite materials were prepared by mixing avocado biochar and methyl polysiloxane (MK). Firstly MK was dissolved in ethanol, and then the biochar was added at different times. In sample 1 (R1), the time of adding biochar was immediately after dissolving MK in ethanol, and in sample 2 (R2), after 48 h of MK dissolved in ethanol. The samples were characterized by nitrogen adsorption/desorption measurements obtaining specific surface areas (SBET) of 115 m² g -1 (R1) and 580 m² g -1 (R2). The adsorbents were further characterized using scanning electron microscopy, FTIR and Raman spectroscopy, adsorption of vapors of n-heptane and water, thermal analysis, Bohem titration, pHpzc, C H N elemental analysis. R1 and R2 adsorbents were employed as adsorbents to remove the antibiotic ciprofloxacin from the waters. The t1/2 and t0.95 based on the interpolation of Avrami-fractional-order were 20.52 and 246.4 min (R1) and 14.00 and 157.6 min (R2), respectively. Maximum adsorption capacities (Qmax) based on the Liu isotherm were 10.77 (R1) and 63.80 mg g -1 (R2) for ciprofloxacin. The thermodynamic studies showed a spontaneous and exothermic process for both samples, and the value of H° is compatible with physical adsorption.

“…The adsorption method is not effective for the treatment of water-soluble substances, and the problems of recovery and regeneration have to be solved. At present, it is widely known that the research on adsorption materials mainly focuses on the improvement of traditional adsorption materials and the research of “green” adsorption materials [ 11 , 12 ]. It is of great significance to develop new adsorption materials suitable for the removal of nitrogen-containing heterocyclic compounds.…”

Modified Shell Powder/La-Fe-TiO2 (La-Fe-TiO2@MSP) composites were fabricated using the sol-gel method and characterized by SEM, XRD, UV-vis DRS and photocurrent techniques, and their physicochemical and optical properties were analyzed. The effects of various factors on the photocatalytic degradation of pyridine and its reaction kinetics were investigated by batch experiments using pyridine, a typical nitrogen-containing heterocyclic compound in coal chemical wastewater, as the target removal species. The pyridine degradation rate of 80.23% was obtained for 800 mg/L composite solution by photocatalytic oxidation of 50 mg/L pyridine wastewater for 180 min at 35 °C, pH = 8 and light intensity of 560 W. The photocatalytic degradation performance was optimal. The quenching experiments determined that the active species of photodegradation were mainly hole and hydroxyl radicals, and the photocatalytic degradation mechanism was analyzed in this way.
