Enhanced adsorption of sulfonamide antibiotics in water by modified biochar derived from bagasse

Abstract

In this study, biochars derived from bagasse were prepared and their ability for the adsorption of four kinds of sulfonamide antibiotics (sulfamethoxazol, thiazole, methylpyrimidine, dimethylpyrimidine) was investigated. Results showed that the modified biochar can efficiently adsorb sulfonamides in water. The biochar obtained at 500oC and modified with 30% hydrogen peroxide was chosen as the adsorbent. Under optimum conditions, pH 4 and 35°C, great adsorption performance was exhibited in the adsorption process of the four sulfonamide antibiotics. The productivity of the modified biochar was ~ 89% compared to un-modified biochar which is ~31%. The successful preparation of biochar from bagasse indicates that it is a good way to reuse the resources. Besides the adsorption of antibiotics, the obtained material also has a great prospect in the removal of other pollutants.

Recent Advances in Using Adsorbent Derived from Agricultural Waste for Antibiotics and Non-Steroidal Anti-Inflammatory Wastewater Treatment: A Review

“…In addition, Qin et al [61] had synthesized BC from sugarcane bagasse and tested for four different kinds of sulfanilamide antibiotics (sulfamethoxazole, thiazole, methylpyrimidine, and dimethylpyrimidine). Under the optimum adsorption condition of pH 4, the derived BC at a 500 • C carbonization temperature and activated with 30% hydrogen peroxide possess the antibiotic removal rate of ~89%.…”

Review of Potential Biochar Utilization on Soil Quality in Agricultural Environments

“…Research related to the removal of tetracyclines and sulfonamides using biochar already exists, but information regarding the adsorption mechanism is still limited (Peiris et al, 2017). The adsorption process is very important to understand the behavior of antibiotic compounds in terrestrial and aquatic environments (Qin et al, 2019). Biochar has been shown to be effective in absorbing various organic contaminants, including drugs and antibiotics, which tend to bind to soil (Jung et al, 2015).…”

“…However, in a two-stage adsorption system, 33.2 g and 22.2 g of magnetic chicken bone biochar were able to remove 96% of tetracycline from waste solution with a concentration of 100 mg L−1 within 180 minutes (Xu et al, 2012). Magnetically derived biochar has been used effectively to extract various antibiotics such as tetracycline, sulfamethoxazole, and other hormones, with adsorption capacities varying between (3.46-169.70 mg g− 1), (5.19-212.80 mg g− 1), and (33.10-297.61 mg g− 1), respectively (Qin et al, 2019;Yi et al, 2019). However, most biochar production techniques tend to be complex and expensive, and approaches that consider only one or two antibiotics are not always adequate (Y.…”

Effective sequestration of levofloxacin from wastewater by biochar-supported manganese dioxide composite: Experimental study and modelling analyses

“…In the infrared spectrum of BSM, the characteristics peaks at 1,071 cm -1 and 1,726 cm -1 are assigned to epoxide rings and carbonyl groups, respectively. The characteristic absorption peaks of hydroxyl (O-H) and amine (N-H) stretching vibrations appears at 3,482 cm -1 and 3,728 cm -1 [9,17,19]. In the spectrum of LEVO-loaded BSM, the above identified functional groups shifted or reduced.…”

“…Presently, several methods have been utilized for the removal of antibiotics including advanced oxidation [3], membrane separation [4], ozonation, photochemical degradation [5], and adsorption processes [6,7]. Adsorption method is considered as one of the most applicable technologies compared to other technologies cited, due to it low cost, no sludge formation, simple operations [1,8,9]. Chitosan, montmorillonite, and graphene-based materials are some of the adsorbents that have been tested for the adsorptive separation of emerging contaminants from water.…”
