Superior removal of humic acid from aqueous stream using novel calf bones charcoal nanoadsorbent in a reversible process

While the potable water disinfection regimen has significantly reduced waterborne diseases, development of disinfection byproducts (DBP) during this process has brought a global threat to the environment and human health. The most notorious water pollutant, humic acid (HA), transforms into carcinoge...
