Abstract An ionic liquid-polyaniline/tungsten disulfide (IL-PANI/WS 2 ) composite was synthesized in 1-butyl-3-methylimidazole tetrafluoroborate (LB104) aqueous solution by in-situ polymerization and characterized Fourier transform infrared spectroscopy. A current-carrying friction wear tester used to study the tribological properties of steel—steel copper—copper pairs lubricated an IL-PANI/WS ...

In this survey adsorption of some heavy metals such as cobalt and lead on montmorillonite and montmorillonite/copper oxide nano-composite is reported. Adsorption percent and adsorption capacity were studied under different conditions such as pH concentration of metal ions amount of clay and interaction time. The results show that an increase in absorption percent and absorption capacity wit...
