3、久性有機(jī)污染物去除效果不夠理想。近年來(lái),天然舍鐵礦物作為催化劑,催化過(guò)氧化氫的化學(xué)治理方法對(duì)各種有機(jī)污染物去除效果顯著。概述近年來(lái)主要含鐵礦物、負(fù)載型礦物和納米礦物材料催化過(guò)氧化氫在地下水有機(jī)污染去除中的應(yīng)用,探討了該領(lǐng)域的發(fā)展現(xiàn)狀和存在問(wèn)題,并對(duì)其應(yīng)用前景進(jìn)行展望。認(rèn)為天然礦物材料具有成本低、在地殼中含量高、環(huán)境友好等特點(diǎn),可用于多種有機(jī)污染物的去除與降解。但處理過(guò)程中,天然有機(jī)質(zhì)的作用、納米礦物材料的毒性和地球化學(xué)歸宿問(wèn)題應(yīng)該做進(jìn)一步研究。關(guān)鍵詞:含鐵礦物;負(fù)載型礦物;納米礦物材料;地下水修復(fù)中圖分類(lèi)號(hào):P619.21
