| 摘 要： | 用慢速滴碱法合成聚合氯化铝的过程中加入酸改性的凹凸棒,制备了新型絮凝剂APAC。采用Al-Ferron逐时络合比色法和烧杯絮凝实验法分别研究了APAC复合絮凝剂中铝的形态分布和絮凝性能。结果表明,Ala随盐基度的升高而逐渐降低;Alb随盐基度的升高而升高;Alc则先随盐基度的升高而升高,达到最大值后,再随盐基度的升高而降低。在相同实验条件下,盐基度愈高,混凝效果愈好,Alb含量愈高,混凝效果并不一定愈好。因此,APAC的质量控制以及追求目标应当是尽量提高Alc的含量,而不是Alb的含量。 |

| Abstract: | A novel environmental flocculant was prepared in the process of accession to polyaluminum chloride by a low-speed alkaline titrimetry with HCl modified attapulgite as the main raw material.The species distribution of aluminium of APAC are analyzed by Al-Ferron complexation timed spectrophotometric method,and the coagulation performance of APAC is also characterized by jar tests.The results show that Ala decreases gradually with the rising of the basicity,while Alb increases with the increase of the basicity... |
| Keywords: | distribution of aluminum form Al-Ferron complexation timed spectrophotometric method complex flocculant coagulative property polyaluminum chloride |
