Sorption of cobalt and nickel on narcissus tazetta l. Leaf powder

Abstract

Narcissus tazetta Linnaeus are grown in the Karaburun district of the Agean Region in Turkey in large quantities. The flower has an economic value; however, the leaves of the plant are of no use. Within this study's scope, sorption behaviors of Narcissus tazetta L. leaf powder against cobalt and nickel ions were investigated by batch experiments. The effects of initial pH, contact time, initial metal concentration, temperature, and biosorbent dosage were examined using one-factor-at-a-time method. Maximum sorption capacities for Co(II) and Ni(II) were 43.48 and 35.97 mg g-1, respectively. The biosorption process is fast, and the equilibrium was attained in 15 min. for Co(II) and Ni(II). Data fit the pseudo-second-order kinetic model well for both metal ions. Thermodynamic parameters reveal that the biosorption is exothermic and spontaneous. Narcissus tazetta L. Leaf powder is a readily available, costless, and promising biomaterial that can be used to separate Co(II) and Ni(II) ions from an aqueous solution.
