    GB/T 6287-2021
    Determination of static adsorbed water for molecular sieve

    GB/T 6287-2021 "Determination of Static Water Adsorption for Molecular Sieves" specifies two testing methods: the saturated sodium chloride solution method and the vacuum adsorption method. It is applicable to the determination of static water adsorption for various granular and powdered molecular sieves. The test requires the use of an electronic balance with an accuracy of 0.001 g, a constant-temperature device with a temperature control accuracy of ±1°C, as well as instruments such as a vacuum desiccator and vacuum pump that meet the requirements. Through steps such as sample pretreatment, adsorption equilibrium, and weighing calculation, the static water adsorption capacity of the molecular sieve is determined, providing accurate data for the evaluation of its adsorption performance.
