Abstract: Several processes/methods of impurities removal during high purity alumina preparation with aluminum alkoxide hydrolysis method were reviewed. These processes can be classified into three categories, i.e., aluminum alkoxide, aluminum hydroxide and alumina. After analysis of their fundamental principles of each process, advantages and disadvantages of every process, including operating parameters, performance characteristics and removal effect, were compared and summarized. Future development of the impurity removal technology was also prospected.

Key words: aluminium alkoxide, alumina, aluminium hydroxide, combination technology, removal of impurity
