Abstract In this study, pumice from different regions of Turkey (Diyarbakir, Southeast and Bitlis, East Turkey) has been supplied used as supporting material for nanoscale zero-valent iron (nFe 0 ). Native Bitlis (NBP)-supported (BP-nFe ) native Diyarbakir (NDP)-supported zero-value (DP-nFe were synthesized under the same conditions. (NDP, NBP) pumice-supported nFe BP-nFe adsorbents morphologic...

Comparison analysis of linear least-square method and non-linear method of three widely used isotherms (Langmuir, Freundlich, and Redlich-Peterson) were examined to experiment with Remazol Red (C.I. 18221) onto pistachio nut shells at a solution temperature of 293 K. All three isotherm equations showed a better fit to the experimental equilibrium data. The results show that the Langmuir model s...

Adsorption plays an important role in water and wastewater treatment. The analysis and design of processes that involve adsorption rely on the availability of isotherms that describe these adsorption processes. Adsorption isotherms are usually estimated empirically from measurements of the adsorption process variables. Unfortunately, these measurements are usually contaminated with errors that ...

The adsorption behaviour of Methyl violet and Auramine yellow from aqueous solution onto Stishovite clay was investigated as a function of parameters such as initial dye concentration, contact time, p and temperature. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms. Adsorption followed pseudo-second order model. The experimental data fitted well ...
