粉(fen)狀(zhuang)活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)具體內容是定量(liang)得(de)(de)(de)活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)在(zai)標(biao)準碘(dian)(dian)(dian)液中吸附(fu)碘(dian)(dian)(dian)得(de)(de)(de)多少，一(yi)般用(yong)來表示活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)對小(xiao)(xiao)分(fen)子雜質的(de)(de)吸附(fu)能(neng)力，實際(ji)對活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)得(de)(de)(de)性(xing)(xing)(xing)(xing)(xing)能(neng)沒有什么意義，也就是說，碘(dian)(dian)(dian)值(zhi)高得(de)(de)(de)活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)不(bu)見得(de)(de)(de)就是好，粉(fen)狀(zhuang)活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)碘(dian)(dian)(dian)值(zhi)表征活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)略大(da)(da)于(yu)1.0nm微孔得(de)(de)(de)發達程度。由于(yu)碘(dian)(dian)(dian)分(fen)子大(da)(da)小(xiao)(xiao)為(wei)(wei)0.6nm左右。碘(dian)(dian)(dian)值(zhi)就表征活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)大(da)(da)于(yu)0.6nm的(de)(de)有機物(wu)的(de)(de)吸附(fu)量(liang)，同(tong)(tong)時也表征了大(da)(da)于(yu)該1nm活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)孔隙的(de)(de)多少。粉(fen)狀(zhuang)活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)碘(dian)(dian)(dian)值(zhi)的(de)(de)檢測(ce)方(fang)法粉(fen)狀(zhuang)活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)作(zuo)為(wei)(wei)一(yi)種優(you)良的(de)(de)物(wu)理、化學吸附(fu)劑，越來越受到人們的(de)(de)重視。隨著活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)用(yong)途的(de)(de)增加，粉(fen)狀(zhuang)活(huo)(huo)(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)的(de)(de)檢測(ce)方(fang)法也越來越多。但不(bu)同(tong)(tong)的(de)(de)檢測(ce)方(fang)法有可能(neng)會發生不(bu)同(tong)(tong)的(de)(de)性(xing)(xing)(xing)(xing)(xing)能(neng)指(zhi)標(biao)。

       碘(dian)值一直(zhi)是評估活性炭(tan)吸附(fu)能(neng)力的(de)標準(zhun)。碘(dian)值越(yue)(yue)(yue)(yue)高直(zhi)徑(jing)在2.0-8.0mm之(zhi)間，大(da)小(xiao)(xiao)誤差在5%之(zhi)間，顆(ke)粒越(yue)(yue)(yue)(yue)細越(yue)(yue)(yue)(yue)小(xiao)(xiao)果殼活性炭(tan)質量越(yue)(yue)(yue)(yue)好(hao)。六個指(zhi)標教你區(qu)分果殼活性炭(tan)的(de)好(hao)壞催(cui)化載體活性炭(tan)。

       杏殼(ke)活性(xing)炭比表(biao)面積:

       比表(biao)面積是(shi)將一(yi)(yi)克果(guo)殼(ke)活性(xing)炭內部(bu)空間產(chan)開呈現一(yi)(yi)個面，這個平(ping)面的面積就是(shi)果(guo)殼(ke)活性(xing)炭的比表(biao)面積，比表(biao)面積大的果(guo)殼(ke)活性(xing)炭質量就越好(hao)。

       機(ji)械強度(du)：機(ji)械強度(du)決定(ding)了果殼活(huo)性(xing)炭的(de)使用(yong)壽命，機(ji)械強度(du)越高，果殼活(huo)性(xing)炭強度(du)就越高，質量(liang)就越好(hao)。

       灰分(fen):灰分(fen)主要是(shi)過客活性炭燒(shao)制后(hou)殘(can)留(liu)物，灰分(fen)越低說(shuo)明果殼活性炭的燒(shao)制過程越規(gui)范，殘(can)留(liu)物也就越少。

       決定果殼活(huo)性炭質量的因素又很多，只有通過各方(fang)面的綜(zong)合對比，才能確保果殼活(huo)性炭的質量。

       粉狀活性炭的(de)(de)微孔(kong)可(ke)以吸(xi)附低分(fen)(fen)(fen)(fen)子(zi)量(liang)的(de)(de)氣體(ti)和(he)溶液中(zhong)(zhong)的(de)(de)小分(fen)(fen)(fen)(fen)子(zi)，但(dan)(dan)分(fen)(fen)(fen)(fen)子(zi)量(liang)較高(gao)的(de)(de)分(fen)(fen)(fen)(fen)子(zi)不能進入(ru)微孔(kong)內，中(zhong)(zhong)孔(kong)提供進入(ru)微孔(kong)的(de)(de)通道，本身(shen)又(you)能吸(xi)附分(fen)(fen)(fen)(fen)子(zi)量(liang)較高(gao)的(de)(de)物質，大(da)孔(kong)則兼有提供通道和(he)吸(xi)附的(de)(de)作用(yong)(yong)。如(ru)果用(yong)(yong)活性炭吸(xi)附小分(fen)(fen)(fen)(fen)子(zi)物質，例如(ru)某些氣體(ti)(毒(du)氣）和(he)低分(fen)(fen)(fen)(fen)子(zi)量(liang)的(de)(de)有機物，可(ke)以使用(yong)(yong)微孔(kong)較多(duo)(duo)的(de)(de)產(chan)品(pin)；但(dan)(dan)如(ru)果要(yao)吸(xi)附較大(da)的(de)(de)分(fen)(fen)(fen)(fen)子(zi)，則要(yao)選用(yong)(yong)有較多(duo)(duo)中(zhong)(zhong)孔(kong)的(de)(de)產(chan)品(pin)。
