      Speciation of hydroxyl polymeric aluminum is very important in the environmental chemistry due to the uncertain toxicity of hydroxyl polymeric aluminum. It has been reported that natural inorganic monomeric aluminum species are toxic to biological systems. However, polyaluminum might be more toxic than monomeric aluminum, because polyaluminum is more easily penetrating into human body and plant. Therefore, the structural characterizations of hydrolytic polymeric aluminum in solutions become the research focuses in the fields of environmental analysis, geochemistry and material catalysis etc. The progresses for studying a few hydroxyl polymeric aluminum crystals designed and synthesized as new environmental materials are reviewed in this paper. Some comparisons and comments were made on the structural characteristic of some typical hydroxyl polymeric aluminum crystals which of structures were well characterized before. Scientific significance and practical application potentials of the new hydroxyl polymeric aluminum crystals were also discussed.
