Study on Adsorption of Cd²⁺ in Solution with HNO₃ Modified flax wastes

Abstract:  In this paper, the widespread flax wastes were used as materials and the flax adsorbent modified with HNO₃ were preparated. Meanwhile, the removed of Cd²⁺ by the flax adsorbent modified with HNO₃ and flax raw were compared. As a result, the optimum pHe value was 5.37and 5.52; S/L was 4.3 g/L; the best touched time is 180min; q_m was 1.12mol/kg and 0.79mol/kg with the flax adsorbent modified with HNO₃and flax raw, respectively. As for the adsorption of Cd²⁺, the HNO₃ modified flax adsorbent has better result than the flax raw material under the same conditions.
