Abstract
In this study, N-doped biochar BZ-9.5AG-30 min was prepared from bamboo by using ZnCl2 as activator and heat treated at 950 °C under NH3 gas flow for the removal of Cr(VI). The adsorbent was characterized by BET, and the amount of intro...

It is well recognized that gas vesicles influence the buoyancy of Microcystis and control the migration in the water column. Some of Microcystis strains do not have gas vesicles, so these strains cannot obtain buoyancy from them. In this study, we...
Adsorbents for phosphate ion removal were prepared with K2CO3 activation and heat treatment at 950 degrees C from poly-acrylonitrile-based carbon fiber (PAN-CF). Comparative tests for specific surface area and pore structures, elemental and nitrog...
