Modification of commercially-available adsorbents with respect to their surface characters and/or micropore structures was studied aiming at achievement of better adsorptive separation of trace component as well as bulk separation and further presentation of design methods for such cases. (1) Removal of odoring gases, e.g., hydrogen sulfide, methyl mercaptan and trimethylamine from air was studied by fixed bed of chemicals-deposited carbon to obtain equili-brium and kinetic data. (2) Chemical vapor deposition (CVD) technique was applied to adjust commercial molecular-sieving carbon in its micropore sizes thus achie-ving higher performance in air separation by pressure swing adsorption. (3) Resin adsorbents were treated to show enough capacity for the separation of amino-acids. (4) Hydroxyapatite powder was used to remove divalent heavy metal ions from water and equilibrium and kinetic data were obtained for agitated-tank and fixed-bed treatment. From these results, some design criteria were established.

本文对现有的吸附剂进行了表面改性和/或表面结构改性研究，旨在实现更好的痕量组分的吸附分离和本体分离，并进一步提出了此类情况下的设计方法。(1)去除恶臭气体，例如，本文用化学沉积炭固定床研究了空气中硫化氢、甲烷和三甲胺的平衡和动力学数据。(2)采用化学气相沉积（CVD）技术对商品分子筛炭进行粒度调整，以提高变压吸附空气分离性能。(3)对树脂吸附剂进行处理，使其具有足够的分离氨基酸的能力。(4)采用羟基磷灰石粉体去除水中二价重金属离子，获得了搅拌槽和固定床处理的平衡和动力学数据。根据这些结果，建立了一些设计准则。
