layer. The highest peak intensity on the doo: plane was achieved as the methenamine content increased until the methenamine content reached 50 mmol/g but then reduced as the content increased to 100 mmol/g. Since the samples characterisation from the XRD pattern shows that there is a chemical interaction betweer methenamine and the interlayer spacing of montmorillonite, there is a need for further investigation to determine the possible configuration based on the chemical interaction.

The possible configuration of methenamine in the interlayer of montmorillonite space in higher content is partial exfoliation as described in Figure 2. Initially, the methenamine molecules in smectite clay went through the intercalation process and as the methenamine content increased, the molecules in the interlayer of montmorillonite space proceed for the partial exfoliation process.

Table 1: Specific surface area, pore volume and pore radius of materials The calculated specific surface areas of the materials are listed in Table 1. Based on the data, the specific surface area of the samples increased as the methenamine content increased until 50 mmol/g. The results are in line with the doo1 change since the Meth/MMt-50 has the highest peak intensity value of 2.03 nm. The surface morphology of the MMt after methenamine intercalation also changed to become flakier as represented in Figure 4. The presence of N indicated from the EDX data suggesting the increase in N content as methenamine increased in varied concentration. Based on the gas sorption analysis data, the specific surface areas of the samples can be determined to identify the effects of increasing the methenamine content on the chemical interaction based on the methenamine intercalation process.

The confirmation on the different conformations is represented by the gas sorption analysis data. Adsorptior desorption curve exhibited in Figure 3 displays the evolution of adsorption-desorption pattern. The graph show an increasing volume profile pattern for every MMt sample. The patterns show that there is an increasin adsorption capacity with methenamine intercalation.
