| 摘 要： | 采用缓（控）释放技术，利用硅藻土、氧化铝、分子筛三种吸附剂来负载高铁酸盐，制成了负载型高铁酸盐缓释剂，并通过条件优化试验，确定出了负载高铁的最佳吸附材料、吸附剂的最佳干燥方式以及最佳负载时间和最佳负载浓度，得到了高铁在一定时间内能缓慢释放，以进行缓释消毒的条件。实验结果表明，负载型高铁酸盐缓释剂具有较高的高铁溶出浓度与持续时间，这一结果为负载型高铁酸盐缓释剂应用于实际水消毒提供了依据。

| Abstract: | In this study, the controlled release technology is adopted to load the ferrate on the sorbents such as diatomite, alumina and molecular screen respectively. The loaded materials, desiccating temperature, the loaded time and concentration of ferrate were optimized. The results show that the diatomite of loaded ferrate can release the ferrate effectively and maintain the higher release time, which will be given as a practical method to be applied in drinking water purification. |
