Abstract:

The purposes of this study are synthesis graphene oxide (GO), SiO2

@C@Graphene composites and check characterization of synthesized GO and

SiO2@C@GO. The crystallite size and phase characteristic of the product were

determined by using the XRD pattern. Compositional analysis of the as-prepared

samples was performed by Fourier transform infrared spectroscopy (FT-IR). The

morphologies and size of the samples were obtained by field emission scanning

electron microscopy (FESEM) and Transmission electron microscopy (TEM).

Analyze the Adsorption properties of samples by using Atomic absorption

spectroscopy (AAS).

Conclusion, SiO2@C@graphene composites prepared here could be a promising

candidate sorbent material for removing heavy metal ions from aqueous. The

outstanding physicochemical properties of the SiO2@C@graphene composites

materials play a very important role in environmental pollution management in the

future of human life.

Keywords GO, SiO2@C@Graphene composites, hydrothermal

adsorption.

ACKNOWLEDGEMENT

Luckily, I have a valuable internship chance to learning and professional

improvement in Department of Biomedical Engineering and Environmental Sciences

in National Tsing Hua University (NTHU), Taiwan.

First of all, I want to thank my supervisors Prof. Ruey-An Doong and Dr. Ho

Ngoc Son, those who took the time out to listen, guide, bolster and support me on the

right way and allowing me to complete my study to have fruitful results. Particularly,

their extremely valuable guidance are not a little commitment in orienting my

professions and future.

Secondly, I am grateful to Nguyen Thanh Binh Ph.D and Miss. Khuat Thi

Thanh Huyen about their help dedicated during my studies and research in this

laboratory. They was hearted guidance, given the comments and the orientation in my

experiment steps as well as the process of writing my report.

I would like to thank my friends in the laboratory for their guidance to use a

variety of important machinery serving my experiments.

Last but not least, thanks to my parents and good friends who always encourage

me and offer support and love.

Sincerely,

Vu Xuan Truong
