The performance of Copper Sulfide (CuS) was evaluated as sorbent material for Permanganate ions (

). The influences of pH,

concentration, sorption time and temperature were inspected. The outcomes of this study approved that the sorbate primary concentration of 1200 mg l−1, solution pH of 1.5, 90 min sorption time and temperature of 60 °C are the optimal conditions for

sorption by CuS. The study also revealed that the kinetic model of second order and model of Langmuir isotherm describe well the experimental data of this sorption. Furthermore, significant sorption capacities of 769.23, 909.09, 1111.11 and 1250.00 mg g−1 were resulted at 20 °C, 30 °C, 40 °C and 60 °C, one-to-one. Additionally, thermodynamic outcomes confirmed that the nature of

sorption by CuS is a heat-absorbing and spontaneous.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
