The invention relates to the fields of separation of mixed gas and purification of feed gas and discloses a high-strength gas purifying and separating adsorbent. CeO2 is introduced into a porous carrier, clay and a caking agent which are loaded with main active components to effectively disperse the main active components. The creative improvement point of the invention is that the CeO2 is effectively introduced into the adsorbent so as to improve the dispersibility of the main active component of Cu<+> or Cu<++> ion, improve the occupation ratio of a metal active center on the surface of the carrier, promote the effective complexation of Cu<+> with CO in the reaction and effectively improve the separation performance of the adsorbent. The CeO2 is introduced to promote an effective silicon and aluminum hydroxyl network to be formed among the carrier, the clay and the caking agent, promote the tight combination among the main active components of the metal ion, the carrier and the caking agent, strengthen the bonding of silicon and aluminum hydroxyl and effectively improve the strength which can reach over 100N. The adsorbent has favorable strength, is beneficial to being applied to a pressure swing adsorption (PSA) device and has improved practicability of wide application.

The invention discloses a functional high molecular sensing material with potassium ion selectivity based on click chemistry and an application thereof. A carrier fixed on an azide group-modified polyvinyl chloride substrate through a Huisgen cycloaddition reaction (commonly referred to as 'click chemistry') can be applied to manufacturing of electrochemical and optical sensors. Due to the formation of a triazole connecting ring in a polymer, the solubility of functional polyvinyl chloride is lowered. A solid phase electrode manufactured by using a plasticized functional polymer has Nernst response to potassium ions in the range of 10-6 to 10-1M, and has very high selectivity. A potassium ion carrier is fixed, so that the service life of a solid phase sensing film is prolonged. The functional polymer can be applied to preparation of an optical sensing film together with a color developing ion carrier ETH 5294. The measuring range and ion selectivity of an optrode can be matched with an ion-selective electrode.
