Abstract
  In this work, Crystal Violet (CV), cationic dye, is removed from aqueous solution, using wood of Argan shell(ARS) and Almond shell (ALS), as low-cost and eco-friendly biosorbants. The parameters influencing the adsorption of CVon each of our adsorbents, contact time (5–180 min), adsorbent dose ...  Read More
