Therefore , according to the changes of recovery rate , the PH value of aqueous solution has a significant effect on the extract that is the magnetic bead of nano-amino . As for the tranquillizer , the rate of recovery can be optimal only at an alkaline pH value .
从回收率中可以看出,溶液pH值对纳米氨基磁珠的萃取有较大影响,安定只有为碱性时才能得到满意的回收率。
