小明在学完《水的净化》后,了解到活性炭(如图1所示)具有吸附性,可以滤去水中的不溶性物质,还可以吸附掉一些溶解的杂质,除去臭味;市场上的净水器,有些就是利用活性炭来吸附、过滤水中的杂质的(图2即为活性炭净水的示意图)。可是小明很好奇的是“活性炭都能吸附哪些物质?活性炭的吸附能力又和什么条件有关系呢?” Xiao Ming learned “purification of water” after learning that activated carbon (shown in Figure 1) has adsorption, can filter out insoluble materials in water, but also can absorb some dissolved impurities to remove odor; the market of water purification Some, is to use activated carbon to adsorb and filter impurities in the water (Figure 2 is a schematic diagram of activated carbon water purification). However, Xiao Ming is very curious is “Activated carbon can adsorb substances? Activated carbon adsorption capacity and what conditions have a relationship?”
