AB  - The shell of Lagenaria vulgaris (LV) plant was used as biosorbent for strontium removal from aqueous solutions. Chemical structure of the biosorbent's surface was characterized by the means of FTIR and Boehm's titrations. SEM-EDX technique was used to study the morphology and elemental composition of the material. The analyses pointed out to abundance of acidic functional groups which are charged in solution and hence responsible for ionic exchange of Sr(II) ions. Sorption was examined by varying initial concentrations of Sr(II) in solutions, sorbent's loadings, pH, and contacting times. Equilibrium of the process was attained in the first 10 min of contacting and followed pseudo-second order and Chrastil's kinetic models. It was established that sorption onto aLVB was heterogenous by nature and fitted well to Freundlich and Sips isotherm models with maximum sorption capacity of 29.55 mg g(-1). Sorption potentail was kept high after six cycles when acidic desorbents were used.

AB  - The removal of copper(II) ion from aqueous solution by the granular activated carbon, obtained from hazelnut shells (ACHS) (Corylus avellana L. var. lunga istriana), was investigated. The ACHS was prepared from ground dried hazelnut shells by specific method carbonisation and water steam activation at 950 degrees C for 2 h. The granular activated carbon produced from hazelnut shells has a high specific surface area (1 452 m(2).g(-1)) and highly developed microporous structure (micropore volume: 0.615 cm(3).g(-1)). In batch tests, the influences of solution pH, contact time, initial metal ion concentration and temperature on the sorption of copper(II) ion on ACHS were studied. The results indicate that sorption of copper(II) ion on ACHS strongly depends on pH values. The adsorption data can be well described by the Langmuir isotherm and Redlich-Peterson model. The monolayer adsorption capacity of the ACHS-copper(II) ion, calculated from the Langmuir isotherms, is 3.07 mmol.g(-1). The time-dependent adsorption of copper(II) ion could be described by the pseudo second-order and Elovich kinetics, indicating that the rate-limiting step might be a chemical reaction. The intra-particle diffusion model indicates that adsorption of copper(II) ions on ACHS was diffusion controlled.
