Malkoc, Emine The biomass of terrestrial-plant materials has high removal capacities for a number of heavy metal ions.
The Ni II biosorption capacity of the cone biomass of Thuja orientalis was studied in the batch mode. The biosorption equilibrium level was determined as a function of contact time, pH, temperature, agitation speed at several initial metal ion and adsorbent concentrations.
The removal of Ni II from aqueous solutions increased with adsorbent concentration, temperature and agitation speed of the solution were increased. According to Langmuir isotherm, the monolayer saturation capacity Q o is The pseudo-first-order, pseudo-second-order and intraparticle diffusion kinetic models were applied to test the experimental data for initial Ni II and cone biomass concentrations.
The pseudo-second-order kinetic model provided the best correlation of the used experimental data compared to the pseudo-first-order and intraparticle diffusion kinetic models. The activation energy of biosorption E a was determined as This study indicated that the cone biomass of T. PubMed Central Background Thuja orientalis has been traditionally used to treat patients who suffer from baldness and hair loss in East Asia.
The present study sought to investigate the hair growth-promoting activity of T. Methods After T. To determine the effect of T. Results We observed that T. Specifically, the histomorphometric analysis data indicates that topical application of T. We also observed increases in both the number and size of hair follicles of the T.
Conclusion These results suggest that T.
