This study investigated the adsorptive removal of target fluoroquinolones and tetracyclines by biochar made by yak dung collected from the Qinghai-Tibet Plateau. Yak dung biochar pyrolyzed at 700 °C possessed surface area of 198.745 m 2 g −1 and multiple functional groups. Effects of different factors including biochar dosage, pH, temperature, and initial concentration on adsorption of antibiotics were discussed. The biochar dosage of 1 g L −1 was preferable for adsorptive removal of antibiotics. Adsorption of target antibiotics did not show pH-dependent features. Adsorption capacities of fluoroquinolones and tetracyclines positively increased with temperature and initial concentration. Pseudo-second order model and the Freundlich model better fitted the experimental kinetic and isotherm data, respectively. Yak dung biochar provides a new idea on resource utilization of solid wastes and pollution control in the Qinghai-Tibet Plateau.

Background. Mining, waste disposal, and agrochemical residues have contributed to pollution of water and soil with toxic metals in most low- and middle-income countries, raising concerns of ecological safety and public health. This has prompted many studies into the production and utilization of biochars to adsorb toxic metal contaminants from soil and water. Objective. The present study presents a review of biochar properties, the mechanisms of toxic metal adsorption onto biochar, and sorption of toxic metal contaminants in water and soil in small scale applications and laboratory experiments. Methods. A total of 305 articles were collected, and after screening for relevance, a final of 164 articles from both high- and low- and middle-income countries were used in this review paper. Discussion. Biochar for sorption has proven effective and its raw materials are readily available, cost effective, environmentally stable and a good form of waste management. Conclusions. Different techniques of biochar production influence the properties of biochar and adsorption of toxic metals from water and soil. Competing Interests. The authors declare no competing financial interests.

In this work, the feasibility of using guava leaves powder (GLP) as an adsorbent to remove ciprofloxacin (CIP) from aqueous solution was investigated. The effectiveness of GLP to remove CIP was studied under different experimental conditions. The optimum pH for the adsorption of CIP was found to be pH 4. The adsorption trend was rapid at the initial stage and equilibrium was achieved in 60 min. The percentage uptake of CIP decreased with increasing initial CIP concentration. The adsorption kinetics was found to conform well to the pseudo-second order kinetic model. Characterisation of GLP was carried out by using field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM) and Fourier-transform infrared (FTIR) spectrophotometry. Both Langmuir and Freundlich isotherm models were applied to describe the equilibrium adsorption data of CIP onto GLP. The maximum adsorption capacity (q m) was found to be 232.56 mg g-1. By applying Plackett-Burman design, contact time and pH were found to be the influential parameters in affecting the uptake of CIP onto GLP.
