Celecoxib was purchased from Perfermker (Shanghai, China); genistein and carbamazepine (IS) were purchased from J&K Chemical (Beijing, China); and carboxy methylcellulose sodium salt (CMC), acetonitrile (ACN), formic acid, and other MS-using chemicals were purchased from Sigma-Aldrich Company (Shanghai, China). The primary standard stock solution of celecoxib (1 mg/ml) and IS (500 ng/ml) used in in vitro experiments were prepared by dissolving in methanol. Celecoxib and genistein used in the in vivo experiment were dissolved by 5% CMC.
The male Sprague-Dawley (SD) rats (240 ± 30 g) were purchased from Shanghai Laboratory Animal Center (SLAC). Before starting experiments, they were raised for three weeks in laboratory to minimize the influence of transportation process.

Coconut, pinenut and walnut shells were obtained from a local market in Beijing. Coal powder and coconut based granular activated carbon were purchased from Zhengzhou Yedao Environmental Protection Co. (China). The biochar and activated carbon were all crushed and sieved into the particle size of about 150-200 mesh (75-100 μm). Iron powder (Fe), ferric oxide (α-Fe₂O₃) and magnetite (Fe₃O₄) were purchased from Sinopharm Chemical Reagent Co., and milled for 2 hours before use. The two typical pharmaceuticals including carbamazepine (CBZ, purity = 97%, water solubility = 121 mg/L; pK_a1 = 2.3, pK_a2 = 13.9; MW = 236) and tetracycline (TC, purity = 98%, water solubility = 170 mg/L; pK_a1 = 3.3, pK_a2= 7.7, pK_a3 = 9.7 and p Ka₄=12; MW = 444), were purchased from J & K Scientific Co.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
