The water produced by the textile industry contains many dyes that have a toxicity to life in the water . among these dyes is the crystal violet tincture. This led to thinking in an efficient way to remove these dyes , several methods have been used including adsorption , it is best if the material used in the adsorption process is inexpensive and readily available . Rice husk treated with succinic acid is an effective, readily available and easy to obtain substance that has been used to remove the crystal violet tincture. The study was conducted using a range of acidic function PH (2-10), and the extent of the change in weight of the adsorbent substance (0.25-2g) , and changing the initial concentration within a range (5-30mg/l) , and a range of time periods (30_240min). it was found that the highest value of adsorption of crystal violet tincture on the surface of rice husk treated with succinic acid was at pH 8,the adsorption dose (1g), with the initial dye concentration of (50 mg/L) and the contact time( 240 min). The electrochemical behavior of the adsorption solution of crystal violet dye with rice husk treated with succinic acid as a surface was also verified using a cyclic voltammeter technique with a different survey speed, an increase in the oxidation and reduction stream was obtained, in addition to appearance of an oxidation peak and a decrease in the reduction .
