Aplikasi Model Oriented Attachment Pada Pertumbuhan Kristal Nanomagnetit (Fe3O4) Yang Disintesis Menggunakan Metode Hidrotermal

Nanomagnetite (Fe3O4) is a material that can be applied as a drug delivery system. The purpose of this study is to determine the effects of synthesis time and concentration of reactants on the nanomagnetite characteristics, as well as the applying oriented attachments model to determine the equation of crystal growth kinetics model. The nanomagnetitte has been successfully synthesized by hydrothermal method from basic ingredients FeCl3, citrate, urea and PEG in to the distilled water. It was reacted in the reactor (autoclave) at the temperature of 210 °C, reactans concentrations of 0,05 M; 0,1 M; and 0.15 M for 3.5 ; 5 ; 7; 9 and 12 hours. Samples were then characterized by XRD, TEM, BET, PSA and VSM.
The characterization results show the concentration and the synthesis time effected the growth of nanomagnetite crystals. The longer synthesis time and the more concentration will increase the size of the crystal diameter and the more uniform the size of the crystal (9-30 nm), also the greater of pore diameter, pore volume and specific surface area. Besides that the distribution of nanomagnetite particles looked uniform, mesoporous, core shell morphology, hydrophilic and superparamagnetic. The size of the experimental crystal diameter resulting from the characterization was in accordance with the crystal oriented attachment growth model with the highest elevation error of only 29 percent. These properties are suitable and very promising in the application of the Drug Delivery System.

Keywords: Nanomagnetite, hydrothermal, nanomagnetite crystal diameter, oriented attachment model
