“…Biochar has been widely used in studies related to the adsorption of heavy metals in different valence states in water bodies . Compared with traditional activated carbon, the main advantage of biochar is that the raw materials for its production are abundant and low-cost, which can be obtained from agricultural biomass and solid waste, resulting in carbon sequestration and the generation of renewable energy. , The biochar yields applied in various fields have been reported to be equivalent to or even higher than those of commercial activated carbon and other much more expensive materials such as CNTs and graphene. ,− Biochar has brought more attention in the field of wastewater treatment as an effective adsorbent of aqueous pollutants, including dyes, organic and phenolic compounds, heavy metals, and active pharmaceutical compounds as anti-inflammatory and antibiotic drugs known for their complex and long-lasting structures. − …”

One of the main products of pyrolysis is char. For the better performance and improvement of its physicochemical properties, it is necessary to make temperature changes. In this study, different temperatures have been tested for the pyrolysis of rice husk, and the biochar obtained from the process went through an evaluation to test its yield in the removal of emerging compounds such as azithromycin (AZT) and erythromycin (ERY). For this, pyrolysis of rice husk has been carried out at temperatures of 450, 500, 550, and 600 °C, and the biochars have been characterized by ultimate analysis and proximate analysis, as well as specific surface area tests. Then, different adsorption tests have been carried out with a 200 mg L −1 drug (AZT and ERY) solution prepared in the laboratory. All biochars have been found to present removal percentages higher than 95%. Therefore, obtaining biochar from rice husk at any temperature and using it in the removal of high-molecular-weight compounds are quite suitable.

“…Also, the cost-effectiveness issue has made adsorption and oxidation methods out of usage. Using membranes might cause damage from the different organic solvents. − Solid-phase extraction or matrix solid-phase dispersion methods usually take a while and have a low selectivity factor.…”

In this study, the solubility data of two-phase systems for tripotassium citrate and potassium sodium tartrate with PEG4000, 3000, 2000, 1000, and 400 g/mol were experimentally obtained. These data were fitted using empirical equations with MATLAB software. Also, the tie-lines were obtained and fitted by the Othmer–Tobias and Bancroft equations. The results were confirmed by UNIQUAC modeling. Tripotassium citrate resulted as the best salt according to the salting-out ability. The 16 experiments were done based on the Taguchi design of experiment (DOE) to extract the tetracycline from an aqueous solution; the results were analyzed with Minitab 18 software. Acetone was used as an adjuvant in this process. Polymer molecular weight and acetone concentration had the greatest effects on tetracycline extraction efficiency. The maximum extraction (99.78%) was obtained at the concentration of 5 ppm of tetracycline and 8 (% w/w) of acetone with PEG400.

“…According to the sales and distribution data reported by U.S. Food and Drug Administration [2], tetracycline (TC) was the most widely used antibiotic that occupied the highest consumption (42%,~5,866,588 kg) in 2016. Given the fact that there was an estimated 10-40% of TC being absorbed by the human body, the majority of TC consumed was expected to be discharged into the aquatic environment [3]. Recent field investigations revealed several alarming facts that high TC concentration was detected in soil (86-199 µg/kg) [4], drinking water (87-97 ng/L) [5], surface water (5.7-8.7 ng/L), ground water (4.4-9.3 ng/L) [6], hospital wastewater (36-1612 ng/L) [7] and municipal wastewater (110-2353 ng/L) [6].…”

Efficient Heterogeneous Activation of Persulfate by Iron-Modified Biochar for Removal of Antibiotic from Aqueous Solution: A Case Study of Tetracycline Removal

et al. 2019

Waste reutilization is always highly desired in the environmental engineering and science community. In this study, Fe-SCG biochar was functionalized by modifying spent coffee grounds (SCG) with magnetite (Fe3+) at 700 °C and applied for the oxidative removal of tetracycline (TC) with the presence of persulfate (PS). The effects of pH, dosage of biochar and sodium persulfate and initial TC concentration on TC degradation were investigated in a batch system. Our results show that higher TC degradation efficiency was obtained at low pH, low initial TC concentration, and at high dosages of PS and biochar. The highest removal efficiency (96%) was achieved by Fe-SCG/PS under the conditions of pH = 2.0, [Fe-SCG] = 2.5 g/L, [PS] = 60 mM and [TC] = 1 mM. The proposed Fe-SCG catalyst could be a promising effective biochar for the remediation of other emerging organic contaminants.
