[ 1 ] - Toxic metal removal from aqueous solution by advanced Carbon allotropes: a case study from the Sungun Copper Mine
The sorption efficiencies of graphene oxide (GO) and functionalized multi-walled carbon nanotubes (f-MWCNTs) were investigated and elucidated to study their potential in treating acid mine drainage (AMD) containing Cu2+, Mn2+, Zn2+, Pb2+, Fe3+ and Cd2+ metal ions. Several layered GO nanosheets and f-MWCNTs were formed via the modified Hummers’ method and the acid treatment of the MWCNTs, respec...
[ 2 ] - Analyzing the effect of gradation on specific gravity and viscosity of barite powder used in excavation mud
Barite is an important additive material to increase the weight of excavation mud. It has been used extensively in the excavation mud industry. The barite particle sizes used in excavation mud is very important. There is a direct relationship between the amount on the sift of 200 and 325 mesh. By reducing particle sizes of the 200 and 325 mesh, the specific gravity of the barite power increased...
