2026 biology talkshow:濾紙色層分析(選修生物II)
from 雷比特生物空中講 · host 雷比特老師
詳盡介紹濾紙色層分析法的科學機制，這是一種利用物質物理特性來分離植物色素的經典實驗技術。其核心原理在於不同分子對展開液的溶解度以及與濾紙間的吸附力差異，導致各色素隨液體上升的速度不一，進而形成獨特的排列順序。特別列舉胡蘿蔔素與葉綠素等成分在濾紙上的分佈特徵，並引入Rf 值（滯留係數）作為定量分析的關鍵指標。 聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址 https://gemini.google.com/share/05092e21dc65 Powered by Firstory Hosting
