Abstract A preparation method of molecular sieve for chromatographic column is characterized by using calcareous layered clay, surfactant, cross-linking agent and water, mixing them, stirring, making cross-linking reaction, ageing for 1-5 hr. under the condition of that pH value is 4-9 and temp. is 70-75 deg.C, then adopting the conventional method including filtering, washing, drying and baking so as to obtain the invented molecular sieve with high thermal and hydrothermal stability.
