A reaction of 800 mesh stellerite and a concentration of 15% hydrochloric acid in a solid to liquid ratio of 1:3 was carried out for 2 h at \(80^{\circ }\hbox {C}\). Most of its impurities were removed. It can be used as precursors for the preparation of high quality zeolite. Zeolite X which is octahedral crystal shape as cube, 96% of the degree of crystallinity has been synthesized hydrothermally from \(n(\hbox {SiO}_{2}/\hbox {Al}_{2}\hbox {O}_{3})=3, n(\hbox {Na}_{2}\hbox {O}/\hbox {SiO}_{2})=1.14\) and \(n(\hbox {H}_{2}\hbox {O/Na}_{2}\hbox {O})=37\) by controlling reaction temperature and time. The synthesis included zeolite X as carriers, chitosan as intermediates, a mass ratio of zeolite X:chitosan:potassium diformate \(=\) 3:1:2 in weight for 2 h at \(40^{\circ }\hbox {C}\). X-ray photoelectron spectroscopy analysis showed hydrogen bond formation by the chitosan amino hydrogen, potassium diformate oxygen and zeolite X oxygen or hydrogen bond formation by free hydroxyl group of zeolite X and oxygen of chitosan’s C–O, indicating effective grafting. Zeolite X sustained-release antibacterial agent was prepared with an inhibition rate of 78.16% by the antibacterial.
