Then, 3 mL of sodium hydroxide solution (30%) was added and the mixture was heated to 60 °C for 2 h. In the meantime, a bentonite solution was prepared by hydrating a quantity of pure bentonite in 10 mL of distilled water at 50 °C. The bentonite suspension was added to the CMG dispersion and left to react for 1 h.

The methylene blue adsorption test measures the amount of methylene blue () adsorbed on montmorillonite in bentonite. The test is one of the most important methods to estimate a quality of the bentonite. Therefore, the test is conducted by most of the bentonite companies such as mining companies, general construction companies and foundries.
