顆粒物水相反應及顆粒物相態

大氣顆粒物中的化學反應影響空氣品質、全球氣候,以及內陸含鐵物質對海洋表面的傳輸。顆粒物在液態、固態和半固態等相態間轉變能影響這些化學反應的進行的程度和快慢。我們通過流動管反應器、水相氧化裝置以及單顆粒懸浮電動力學天平等技術,模擬實際環境中進行的各種化學過程,獲取反應機理和動力學等參數,為後續的模式類比提供重要的基礎。

水-氣介面的傳質和反應

海洋-大氣的表面特性和化學過程影響海-氣交換,承載著兩個重要圈層物質流通的重要功能。我們通過實驗室模擬、外場觀測等方法,研究介面中的不同成分(如有機物)在介面傳質和反應過程中的作用,結果將有助於更好地理解近海區域的空氣品質和氣候變化的背後機理。
