Titanium (IV)
oxide (anatase, 99.5%, Sigma-Aldrich), chlorosulfonic acid ClSO3H (99%, Sigma-Aldrich), dichloromethane (Prime Chemicals Group),
(NH4)6Mo7O24·4H2O (98%, Prime Chemicals Group), hydrogen peroxide H2O2 (50 wt %, “Prime Chemicals Group”), dodecane n-C12H26 (99%, “Labteh”),
and dibenzothiophene (DBT) C12H8S (98%, Sigma-Aldrich)
were used as received. As a real raw material, a sample of a straight-run
diesel fraction of 240–320 °C, previously extracted with
dimethylformamide, with a total sulfur content of 5250 ppm, was used
in this work.

Synthesis and Characterization of Dye Compounds

Check if the same lab product or an alternative is used in the 5 most similar protocols
All of the purchased chemicals were of at least reagent grade and were used without further purification. Triptycene (98.0%), anhydrous ferric chloride (FeCl3, ≥98.0%), 1,2-dichloroethane (DCE, 99.8%), formaldehyde dimethyl acetal (FDA, ≥98.0%), and chlorosulfonic acid (ClSO3H, 99%) were purchased from Sigma-Aldrich. All of the other solvents were purchased from TCI America. The methylene blue (MEB, 99%), basic fuchsin (BF, 98%), and malachite green (MG, 98%), were purchased from Macklin Biochemical Co. Ltd. (Shanghai, China), and the above three dyes were used without further purification. Their structures are shown in Fig. 1.

Sulfonated Biochar for Antibiotic Adsorption

Check if the same lab product or an alternative is used in the 5 most similar protocols
Two commercial biochars prepared from Ageratina adenophora (grass) and Quercus dentata (oak wood) at 400 o C were procured from Xiyu Biotech Co., Ltd. (Panzhihua, Sichuan Province, China) and Gangwon Charmsoot Company (Hoengseong-gun, Gangwon Province, South Korea), respectively.
They were labeled as X and H, respectively. The raw biochars were milled, and sieved through a 0.25mm mesh before sulfonation. Spiramycin (98%, HPLC standard) was purchased from Dr. Ehrenstorfer GmbH (Germany). Chloroform, concentrated H2SO4 (98%), chlorosulfonic acid (ClSO3H; 99.5%), and p-toluenesulfonic (TsOH, AR) were purchased from Sigma Aldrich (USA). Ultra-pure water (18.2 M•cm) was obtained using a Milli-Q purification equipment (Millipore, USA).

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.
