Preparation and characterization of zeolite A-basalt fiber composite

AbstractBy adjusting n(Na2O)/n(SiO2) and crystallization time, zeolite A - basalt fiber composite was successfully prepared by direct loading method under the system composition of n(SiO2)/n(Al2O3)=2, n(H2O)/n(SiO2)=125, n(Na2O)/n(SiO2)=2.1. The samples were determined by XRD, SEM, FTIR and calcium ion exchange. The results show that the composite of fiber and zeolite A is a combination of structure, and the crystallization time will affect the morphology of zeolite and composite effect. After crystallization for 6h, zeolite A with high crystallinity and moderate particle size can be obtained. At the same time, the loading ratio of zeolite on the fiber surface reaches the maximum, but the alkaline environment will reduce the fiber strength.Keywords: zeolite Abasalt fiberzeolite A- basalt fiber compositeion exchange Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was financially supported by the Fund from the Innovation Capacity Grant Project for Master Degree Candidate in Hebei province (CXZZSS2022019), the science and technology project of Hebei Education Department (BJK2023040), and the Central Government Guide Local for Scientific and Technological Development (206Z1501G).
