摘要
The nanoparticle based on natural bentonite from Pahae village had been prepared using co-precipitation method. Bentonite was dried in the oven at 100 degrees C during a week. Bentonite is crushed using a mortal and milled by planetary ball mill to obtain the powder form. Further, the bentonite powder is activated with chemical reaction by dissolves the 50 g bentonite to 100 ml of HCl at 10 M. The magnetic stirrer was employed to mix the solution at 300 rpm and temperature 70 degrees C. After that, the bentonite solution is washed using distilled water until the pH is neutral. The bentonite powder is calcined at temperature of 600 degrees C for 1 hour with fix increment 150 degrees C. Finally, the powder is given High Energy Milling (HEM) treatment for 30 minutes to obtain the particle size. The X-ray Difractometer (XRD) and Scanning Electron Microscope (SEM) were used to characterize. From the characterization results it is reported that the average of bentonite nanoparticle size is 35.26 nm and the chemical constituents of natural bentonite Pahae are Al, Si, Ca, Fe and Ti.
