實(shí)驗(yàn)中，研究人員將鋁基量子點(diǎn)吸附劑用于鉛礦冶煉廠，發(fā)現(xiàn)1克吸附劑可處理2噸鉛離子濃度達(dá)1000微克/升的污水，遠(yuǎn)高于市售活性炭，且5秒鐘左右即可去除99.9%的重金屬，5分鐘左右使重金屬濃度低于1微克/升，達(dá)國(guó)家飲用水標(biāo)準(zhǔn)。
據(jù)測(cè)算，在同等水體重金屬污染條件下，活性炭的需用量達(dá)1.6至3.3噸，量子點(diǎn)吸附劑僅需100公斤。盡管其價(jià)格較普通吸附材料稍高，但其吸附容量達(dá)數(shù)十倍，綜合運(yùn)行成本遠(yuǎn)低于常規(guī)吸附材料和傳統(tǒng)絮凝沉淀法。
