摘　　要：选择天然贝壳,经清洗、干燥、灼烧、研磨和过筛,制的天然贝壳粉。以TiCl4溶液浸渍,经水解、过滤、清洗、干燥和灼烧,制的载有TiO2的贝壳粉材料。以此种材料为催化剂,考察其对有色的玫红酸分解作用。对比实验表明,载有TiO2的贝壳粉材料,对玫红酸有明显的降解作用。Natural shells were treated in turns by washing,drying,firing and grinding,the natural shell powders were silted out.After dipping in a solution of titanium tetrachloride,sufficient hydrolyzing,washing,drying and firing,the shell powder materials loaded with titania were prepared.Using these titania loaded materials as catalysts,the degradation of colorful rosolic acid was examined.Contrast experiments indicated that the titania loaded materials provided obviously catalytic efficiency during degradation of rosolic acid.
