Green water-purification system works without heavy metals or corrosive chemicals
Scientists at the Institute of Process Engineering (IPE) at the Chinese Academy of Sciences in Beijing and Yangzhou University (YZU) in Jiangsu have developed an effective and energy-efficient technique for purifying water by using graphitic carbon nitride sheets. Their prototype, presented February 7 in the journal Chem, purified pathogen-rich water in 30 min, killing over 99.9999% of bac
