摘要：

Solanum incanum leaves, new and valuable biomass were utilized as sorbent material for the removal of U (IV) ions from aqueous wastes. The leaves of solanum incanum were analyzed by SEM, XRD, EDS and FTIR analyses. Solanum incanum leaves have a good ability to (VI) uptake. The maximum biosorption capacity of SNL was 39.98 mg/g at pH 4 and 45 degrees C. 99.95% of U (VI) ions were biosorbed within 60 min in an endothermic (Delta H:167.267 KJ mol(-1)) batch system. The linear and nonlinear results of biosorption isotherms and kinetics indicate that Langmuir and second pseudo order models were an agreement with the experimental results. Also, the regeneration and reusing of biomass give acceptable results up to 8 cycles of the biosorption-desorption system. (C) 2020 The Authors.
