In this study, AlPO-34, like-chabazite zeolite, was synthesised by ionothermal method using the 1-ethyl-3-methylimidazolium chloride [EMIMCl], ionic liquid compound which acts both as solvent, structure-directing and a functionalising agent. All the characterisation methods used confirm the formation of AlPO-34 structure with [EMIMCl] inserted inside the porous framework leading to a unit cell formula of [(Al 6 P 6 O 12 ) .2 F − .2[C 6 H 11 N 2 ] + ]. 12H 2 O. (15[C 6 H 11 N 2 Cl]). The SEM analysis shows a cubic twinning morphology with an average particles diameter of 20 μm. The obtained ionic liquid-functionalised AlPO-34 material was used as antibacterial agent against Escherichia coli pathogenic bacteria using the dilution method. The results show that this AlPO-34 material inhibited effectively the bacteria proliferation from the media with a minimum inhibitory amount of 2 mg of the material reaching an antibacterial efficacy rate as high as 100%.
