Our present study, we impregnated Al-Fe-Mg-Si (NFM) nanocomposites having various concentrations 0, 1000, 3000, and 5000 mg/L in biomass in order to make carbonized biomass. We characterized the properties of the impregnated samples through thermogravimetric/differential thermal analysis (TG-DTA), pore distribution, scanning electron microscopy (SEM). The best results were observed for a NFM nanocomposites concentration of 5000 mg/L. After the first heat treatment, carbonization, and activation processes, the fixed carbon ratio and iodine adsorptivity were increased by 21.89% and 368 mg/g, 23.98% and 475 mg/g, 26.40% and 238 mg/g, respectively. The remove rate of malodorous and VOCs were that the sample shows good removal capabilities. From above results, our sample could be used for the removal of noxious and malodorous gases and for the purification of wastewater.

제안 방법
We dried the Platycarya strobilacea branches sample at 100 ℃ for 8 hr until the moisture content was less than 5 wt. % and then, used the micelle method to impregnate the NFM nanocomposites into the sample with a volume ration of 1:1.6. During impregnation, the sample was maintained at 40 °C for 120 min, following which it was dried using a drier at 120 °C for 8 h until the moisture content was less than 5 wt.
The proximate analysis was used the KS 1082 to test and investigate the moisture content of the sample, along with the fixed carbon ratio, hardness, packing density, pH, loss on drying, and ash content. Also, the thermo gravimetric analysis was used the Mettler Toledo TGA851 to conduct the heat analysis. During pyrolysis, the sample temperature was increased from 30 to 600 °C at a rate of 10 °C/min.
Also, we determine the remove rate of VOCs (benzene, toluene and formaldehyde), we used a carbonized sample (600 °C / 2 hr) and conducted a remove rate test using the impregnated to NFM 5000 mg/L of nanocomposites.
In order to determine the remove rate of ammonia, hydrogen sulfide and triethylamine, we used a carbonized sample (600 °C / 2 hr) and conducted a remove rate test using the impregnated to NFM 5000 mg/L of nanocomposites.
