客体物质对吸附剂结合位点的接近决定了材料的金属结合能力，这在例如环境修复工作中是重要的。结果表明，MP-HMS（分子筛HMS的巯基丙基硅烷官能化衍生物）具有规则的孔结构，是比硅胶更好的Hg 2+吸收剂，其中官能化导致孔堵塞（见图）。
The access of guest species to the binding sites of adsorbents determines the metal-binding capacity of materials, which is important for example in environmental remediation efforts. It is shown that MP-HMS, the mercaptopropylsilane-functionalized derivative of the molecular sieve HMS, with its regular pore structure is a much better Hg2+ absorbent than silica gels, in which functionalization leads to pore blocking (see Figure).
