土臭素和2-甲基异麦芽糖醇（2-MIB）是天然存在的化合物，导致地表水供应中的泥土霉味。它们是全世界公用事业面临的一个严重问题。粉末活性炭（PAC）吸附是一种广泛使用的控制该问题的方法，但其效率低，这导致公用事业服务的大量预算支出。超细粉末活性炭（S-PAC）是一种比PAC颗粒更细的活性炭。研究了S-PAC和PAC对土臭素和2-MIB的吸附性能。土臭素和2-MIB的吸附容量在S-PAC上不小于PAC上的吸附容量，虽然天然有机物，这对土臭素和2-MIB的吸附容量产生不利影响，在S-PAC上比在PAC上吸附更多，这意味着吸附竞争不太严重的S-PAC比PAC。
Geosmin and 2-methylisoborneol (2-MIB) are naturally occurring compounds responsible for musty-earthy-odors in surface water supplies. They are a severe problem confronting utilities worldwide. Adsorption by powdered activated carbon (PAC) is a widely used process to control this problem, but it has low efficiency, which engenders large budget spending for utilities services. Super-powdered activated carbon (S-PAC) is activated carbon with much finer particles than those of PAC. Experiments on geosmin and 2-MIB adsorptions on S-PAC and PAC were conducted. Geosmin and 2-MIB adsorption capacities on S-PAC were not smaller than those on PAC although natural organic matter, which adversely impacted the adsorption capacity of geosmin and 2-MIB, was more adsorbed on S-PAC than on PAC, meaning that the adsorption competition is less severe for S-PAC than for PAC.
