WebApr 11, 2024 · The desorption of MB-laden DBC and FDBC were tested using 10 mL of methanol (organic), NaOH (basic), and H 2 O 2 (redox) at 25 °C and pH 6.8 (adsorbent-eluent ratio, 25 g/L). Adsorption after regeneration was conducted using 25 mL MB (500 ppm) solutions (adsorbent-adsorbate ratio, 25 g/L) for 3 h (200 rpm) at pH 6.8. WebThe concentration of an acid solution can be determined by titration with a strong base. First, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid.
