Thanks raiderup... but if as Dr Majumder states that SS can be produced at room temperature ie saving on energy costs in production...why then must it be heated to 105c, which would up the energy bill?

I must admit if it shows comparable performance to existing carbon materials as stated, but because it can be synthesized at room temperature and from cheap graphite sources (not too cheap one would hope if one owns SER shares) it would seem from Gao's statement below that the first saving has gone out the window.

“This material demonstrates comparable performance to some commercially available activated carbon materials,” says Dr Mainak Majumder from Monash University in Melbourne, Australia. “But given that this can be synthesized using room temperature processes and also from cheap graphite sources, it is likely to be cost-efficient,” he adds.
Gao explains the technique they used to produce the super sand. She says it involves dispersing graphite oxide into water and mixing it with regular sand. “We then heat the whole mixture up to 105C for a couple of hours to evaporate the water, and use the final product – ‘coated sand’ – to purify polluted water.”
