超声水处理过程中木材内部抽提物迁移规律探究
Study on the Migration Law of Extracts in Wood during Ultrasonic Water Treatment
[目的]观察未处理臭椿材中抽提物的分布,探究超声水处理对臭椿材苯醇抽提物和热水抽提物含量的影响,并分析超声水处理过程中臭椿材内部抽提物在超声传播方向上的迁移。[方法]通过体式显微镜、光学显微镜、扫描电镜观察未处理臭椿材抽提物的分布;以时间为变量(间隔 30min)对臭椿材进行超声水处理(320 W,25 kHz),并进行热水和苯醇抽提实验,探究超声水处理对热水抽提物和苯醇抽提物含量的影响;在比色皿路径为 1 cm,波长为 350 nm条件下,用紫…查看全部>>
[Objective]This study aimed to observe the distribution of extracts,investigate the impact of ultrasonic water treatment on the contents of benzene alcohol extracts and hot water extracts,and analyze the migration of extracts in the direction of ultrasonic propagation during ultrasonic water treatment for Ailanthus altissima wood.[Method]The distribution of extracts in untreated samples was observed using stereo microscopy,optical microscopy,and scanning ele…查看全部>>
