       碘值(zhi)一直是評(ping)估活性炭吸(xi)附(fu)能(neng)力的標準。碘值(zhi)越(yue)(yue)高(gao)直徑在2.0-8.0mm之(zhi)間，大(da)小誤差(cha)在5%之(zhi)間，顆(ke)粒越(yue)(yue)細越(yue)(yue)小果殼活性炭質量(liang)越(yue)(yue)好。六(liu)個指標教你(ni)區分果殼活性炭的好壞催化載體活性炭。

       杏殼活性炭比表面積:

       比表(biao)面積(ji)(ji)(ji)是將一克果(guo)殼(ke)活(huo)性炭內部空間(jian)產開呈現一個面，這(zhe)個平面的面積(ji)(ji)(ji)就是果(guo)殼(ke)活(huo)性炭的比表(biao)面積(ji)(ji)(ji)，比表(biao)面積(ji)(ji)(ji)大的果(guo)殼(ke)活(huo)性炭質量(liang)就越(yue)好。

       機(ji)械(xie)強度：機(ji)械(xie)強度決定了果殼(ke)活(huo)性炭的使用壽命，機(ji)械(xie)強度越(yue)(yue)高，果殼(ke)活(huo)性炭強度就(jiu)(jiu)越(yue)(yue)高，質量就(jiu)(jiu)越(yue)(yue)好。

       灰(hui)分(fen):灰(hui)分(fen)主要是(shi)過客活性(xing)炭燒制(zhi)后殘留(liu)物(wu)，灰(hui)分(fen)越(yue)低說明果殼(ke)活性(xing)炭的燒制(zhi)過程(cheng)越(yue)規范，殘留(liu)物(wu)也就越(yue)少。

       決定果殼活性炭質量的因素(su)又很多(duo)，只有通過(guo)各方(fang)面的綜(zong)合對比，才(cai)能確保果殼活性炭的質量。

       粉狀活性炭的(de)微(wei)(wei)孔(kong)(kong)可(ke)以(yi)吸(xi)(xi)(xi)附低分(fen)(fen)子(zi)量(liang)的(de)氣體和(he)溶液中(zhong)的(de)小分(fen)(fen)子(zi)，但(dan)(dan)分(fen)(fen)子(zi)量(liang)較(jiao)高的(de)分(fen)(fen)子(zi)不(bu)能(neng)進入微(wei)(wei)孔(kong)(kong)內，中(zhong)孔(kong)(kong)提供(gong)進入微(wei)(wei)孔(kong)(kong)的(de)通(tong)道，本身又能(neng)吸(xi)(xi)(xi)附分(fen)(fen)子(zi)量(liang)較(jiao)高的(de)物質(zhi)，大孔(kong)(kong)則(ze)(ze)兼有(you)提供(gong)通(tong)道和(he)吸(xi)(xi)(xi)附的(de)作用(yong)(yong)。如果(guo)用(yong)(yong)活性炭吸(xi)(xi)(xi)附小分(fen)(fen)子(zi)物質(zhi)，例如某些氣體(毒氣）和(he)低分(fen)(fen)子(zi)量(liang)的(de)有(you)機物，可(ke)以(yi)使用(yong)(yong)微(wei)(wei)孔(kong)(kong)較(jiao)多的(de)產品(pin)；但(dan)(dan)如果(guo)要吸(xi)(xi)(xi)附較(jiao)大的(de)分(fen)(fen)子(zi)，則(ze)(ze)要選用(yong)(yong)有(you)較(jiao)多中(zhong)孔(kong)(kong)的(de)產品(pin)。
