【摘要】:為了實(shí)現(xiàn)生活飲用水中金屬鋁元素的快速檢測(cè),試驗(yàn)制作了鋁的檢測(cè)試紙,并對(duì)其進(jìn)行了應(yīng)用性驗(yàn)證。將試紙于浸泡液中浸泡10 min,經(jīng)過(guò)兩次浸泡,60℃下干燥15 min,放入光電測(cè)色儀中,在波長(zhǎng)560 nm下檢測(cè),反應(yīng)時(shí)間為6 min。所得到的標(biāo)準(zhǔn)曲線在0~1μg/m L的鋁含量范圍內(nèi)有較好的線性關(guān)系,該方法的相對(duì)標(biāo)準(zhǔn)偏差在1.66%~4.78%之間,加標(biāo)回收率為94%~98%。試紙法與鉻天青S分光光度法檢測(cè)結(jié)果兩者之間差異無(wú)統(tǒng)計(jì)學(xué)意義(p0.05)。該方法具有檢測(cè)靈敏、快速方便等優(yōu)點(diǎn)。
