Abstract
The present application belongs to the technical field of lithium adsorbent particle cleaning, and specifically discloses a cleaning agent and a cleaning method for lithium adsorbent. The present application provides an efficient and comprehensive adsorbent particle cleaning method, aiming to restore the adsorption performance of the adsorbent and prolong its service life. The method comprises four steps of preliminary cleaning, organic matter and microbial contamination removal, inorganic matter removal and impurity ion removal. The preliminary cleaning removes physical impurities by using a roller device and continuous water feeding; then a compound solution containing a surfactant is used to remove organic matter and microbial contamination; an acid solution is prepared to remove inorganic matter; finally, a chelating agent is prepared and the pH value is adjusted to remove impurity ions. The method realizes comprehensive and deep cleaning of the surface of the adsorbent by accurately controlling the conditions and parameters of each step, while paying attention to protecting the structure and performance of the adsorbent.
