重金属污染土壤添加骨炭对苗期水稻吸收重金属的影响 - In this paper , research on the use of activated alumina and bone char was dong on both batch reactor and continuous - flow column
为了探索合理的除氟方法和工艺，本论文对活性氧化铝和骨炭除氟性能进行了系统的研究。 - The effective regeneration procedure is soaking the adsorbent 30 ~ 50h with 1 - 2 % al2 ( so4 ) 3 for activated alumina and 20 ~ 30h with 1 - 1 . 5 % naoh for bone char . studies show both activated alumina and bone char are excellent adsorbents for the removal of fluoride from drinking water . fluoride concentration below 1 . 0mg / l can be acquired easily with them and meets the requirement of drinking water standards
对两种除氟剂进行的再生液与吸附剂体积比为1 : 1的再生实验表明：用硫酸铝溶液对活性氧化铝再生，再生浓度为1 2 ，再生时间为30 50h ，冲洗浸泡时间为5h效果较好；对骨炭再生，氢氧化钠再生液浓度为1 1 . 5 ，再生时间为20 30h效果较好。 - Adsorption isotherm of activated alumina and bone char can be described by langmuir adsorption isotherm in the form qe = 0 . 72cy ( l + 0 . 074ce ) and freundlich isotherm in the form qe = 0 . 88ce1 / 1 . ' 94 respectively . continuous - flow column experiments show there have higher removal capacity for activated alumina and bone char when empty - bed contact time was controlled within 12 ~ 15min and about 15min separately
对可利用吸附容量和实际利用吸附容量的理论分析说明，连续处理活性氧化铝停留时间控制在12 15min较好，此时吸附容量利用率较高，约为80 ，骨炭停留时间控制在15min较好，吸附容量利用率约为75 。
