Check if the same lab product or an alternative is used in the 5 most similar protocols
The vanadium (V) oxytripropoxide (98%, Sigma Aldrich, Saint Louis, MO, USA), anhydrous ethyl alcohol (99.8%, POCH, Gliwice, Poland), anhydrous 2-propanol alcohol (99.5%, Sigma Aldrich, Darmstadt, Germany), acetylacetone (99%, Alfa Aesar, Kandel, Germany), and methylene blue (82%, Chempur, Piekary Slaskie, Poland) were used without further purification. MiliQ water (0.05 µS cm−1) was used in all experiments.

Methylene Blue Adsorption on Wheat Bran

Check if the same lab product or an alternative is used in the 5 most similar protocols
All reagents, methanol (Merck), hydrochloric acid (HCl—35%), sodium hydroxide (NaOH), sodium carbonate (Na2CO3) and sodium bicarbonate (NaHCO3) obtained from Standard (Poland), were analytical grade and commercially available. The methylene blue (M = 319.86 g/mol; λmax = 663–667 nm) was obtained from Chempur (Poland). The wheat bran used as a precursor came directly from the grain milling in the household.

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.
