Our product combines coarse sand with functional carbon material that could offer higher retention for those pollutants, and at the same time gives good throughput," explained the researcher

She said that the technique the team has developed to make the sand 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."
Cost-efficient
"Super sand" is made using regular sand - and it could become a low-cost way to purify water
The lead scientist of the study, Professor Pulickel Ajayan, said it was possible to modify the graphite oxide in order to make it more selective and sensitive to certain pollutants - such as organic contaminants or specific metals in dirty water Serviced apartment.
