求翻譯:The pH of aqueous solution has been identified as the most important variable governing heavy metal adsorption onto adsor-bent. This is partly because hydrogen ions themselves are strongly competing with adsorbates. Fig. 5 indicates the effect of pH on the removal of copper(II) ions onto HQ-bentonite from aqueous solut是什么意思?![]() ![]() The pH of aqueous solution has been identified as the most important variable governing heavy metal adsorption onto adsor-bent.

水溶液的pH值已被確定為最重要的執(zhí)政重金屬吸附到廣告或彎的變量。這部分是因?yàn)闅潆x子本身的強(qiáng)烈競(jìng)爭吸附。圖5表示的pH值對(duì)銅(II)離子從水溶液到HQ-膨潤土去除效果。結(jié)果表明,當(dāng)pH值增加了表面電位和氫離子的競(jìng)爭減少,這些結(jié)果也支持zeta電位測(cè)量。從圖中可以看出。 5that的吸附能力是在強(qiáng)酸性介質(zhì)中(pH值1.5-2)為零。 PH后2,攝取大幅增加,pH值5.5,因?yàn)楦嗟慕饘俳Y(jié)合位點(diǎn)可能會(huì)暴露,并進(jìn)行負(fù)電荷,帶正電荷和吸附金屬離子的后續(xù)吸引力,到吸附劑表面的。實(shí)驗(yàn)進(jìn)行了pH值到5.5由于金屬降水出現(xiàn)在較高的pH值[32]。

在ph值的水溶性解決方案已被確定為最重要的變數(shù)理事重金屬吸附到adsor的彎曲。 這種情況,部分原因是氫離子與adsorbates本身強(qiáng)烈競(jìng)爭。 圖。 5表示ph的就清除銅(ii)離子到hq-膨潤土、水溶性的解決方
