Hello! I am Johnny Xiao Hong Yu from Singapore. I’m 16 years old and a Secondary 4 student at Hwa Chong Institution. I live with my parents and I have an older brother studying overseas. Personally, I have a strong interest in science and technology. I am a part of my school’s Science and Math Talent Programme, where I have the opportunity to learn more in the field of science and engage in scientific research projects. I am also actively involved in my school’s student’s council, and I am the President of Hwa Chong Institution’s High School Council. I am also a part of my school’s Infocomm Club, as I also have an interest in computers and programming.
Tell us what the water concern in your country is!Singapore’s main water concern is managing our limited water supply. Singapore depends on 4 main domains for our water supply, which are local catchments, imported water, desalination and NeWater. Hence, the main concern is being able to find new ways to increase our water supply and keep it sustainable.
A Novel, Eco-friendly Synthesis of Reduced Graphene Oxide (rGO) from Durian Rind and Sugarcane Bagasse for Water Filters
The conventional method of synthesizing reduced graphene oxide (rGO), a promising material for water purification, is expensive and produces toxic gases. In this study, rGO was synthesized from durian rind and sugarcane bagasse using a novel, eco-friendly, simple and low-cost process. The rGO synthesized from durian rind was comparable to commercial activated carbon in removing methylene blue, a toxic dye, and is 32% more effective than commercial activated carbon in adsorbing copper(II) ions. The rGO synthesized can be incorporated into filters for the removal of dyes and metal ions.
