• Aug 1, 2025 astm methylene blue test for activated carbon lue Adsorption The amount of methylene blue adsorbed per gram of activated carbon (q) is calculated as: \[ q = \frac{(C_0 - C_t) \times V}{m} \] Where: \( C_0 \) = initial dye concentration (mg/L) \( C_t \) = dye concentration after contact time (mg/L) \( V \) = volume of By Sean McClure Sr.
