Description Novel functionalised adsorbents have been synthesized by immobilization of various amines on synthetic
zeolite 13X. Various primary and secondary amines namely monoethanolamine (MEA), ethylenediamine
(ED) and isopropanol amine (IPA) have been immobilized on zeolite 13X. Quantitative estimations of the
amine loadings were undertaken using different analytical techniques namely titrimetric, total organic
carbon and gas chromatography analysis. Fairly good correlation was obtained for amine loadings estimated
using the three techniques. Effect of various parameters like effect of solvent, shaking time, synthesis
temperature, and wetting of pellets prior to amine loadings was also studied. The results revealed
that maximum loading was achieved for methanol-mediated synthesis conducted using previously wetted
pellets at room temperature and with 15 min of shaking time. Preliminary attempts have also been
made to determine the CO2 adsorption capacities of these newly developed materials. The adsorption
capacities obtained were 16.01 mg/g for unmodified zeolite 13X and 19.98, and 22.78 mg/g for zeolite
modified with monoethanol amine, and isopropanol amine.
