[0033] 1.1. Preparation of resin extracts of Jiujielong and banyan tree
[0034] The Soxhlet extraction method commonly used in the art was used to obtain the resin extracts of 9-joint dragon and banyan tree. Specifically, firstly, the pulverized leaves of Nine-joint Dragon or Banyan Bengal were filled into a casing (Thimble) with 20 volume percent of hexane or ethanol ether, heated at a temperature of 120° C., and refluxed for extraction. The heated solvent was refluxed 3 to 10 times to extract the resin of the crushed nine-jointed dragon or bangal banyan leaves, and filtered with 250 mesh and 0.5 μm filter paper to obtain a liquid phase extract. The extracted dry matter is obtained from the filtered liquid phase extract by using a rotary decompression concentrator and a freeze dryer. The dried extract was diluted to 10% by weight with medium-chain triglycerides, and filtered using 250 mesh and 0.2 μm filter paper to obtain a liquid-phase...
Embodiment 1
[0041] Example 1: Confirm the removal effect of the resin extracts of Jiujielong and Banyan banyan tree on heavy metals
[0042]In order to confirm the effect of the resin extracts of Jiujielong and Banyan Bengal on the removal of heavy metals, the same amount of lead (60ppm) and cadmium (30ppm) solutions and the above resin extracts were mixed in a separatory funnel and reacted three times. After three reactions, only the lead and cadmium solutions were separated, and the residual heavy metal content of the separated solution was measured by inductively coupled plasma mass spectrometry (ICP-MS). At this time, as a control group, a group reacted with medium-chain triglyceride was used. The adsorption rate is the concentration of the sample after absorbing heavy metals divided by the concentration of the control sample. The higher the adsorption rate, the stronger the adsorption capacity for heavy metals. The above heavy metal removal rate is (1-adsorption rate)×100.

[0046] Example 2: Confirming the decomposition effect of the resin extracts of Jiujielong and banyan banyan on fine dust
[0047] In order to confirm the decomposing effect of the resin extract of Kujielong and Banyan banyan on fine dust, 1% of fine dust (PM10) captured by a high-efficiency particulate air (HEPA) filter was mixed with the above extract, and the ultraviolet-visible light was used to (UV / VIS) spectrophotometer to measure the transmittance of different time periods at 550nm. At this time, as a control group, a group containing only medium-chain triglycerides was used. The transmittance of fine dust is divided by the transmittance of the sample containing fine dust divided by the transmittance of the control sample. The higher the transmittance, the stronger the ability to decompose fine dust. The decomposition rate of the above-mentioned fine dust is (1-transmittance)×100.
[0048] The analysis results show that the longer the treatment time of the resin extrac...
