Natural zeolites cropped out from Pâglisa (Romania) (P), were evaluated in the process of iron removal from model solutions. Experimental data were evaluated using linear and non-linear regression analysis. A comparison analysis between the two regression methods for estimating the isotherm parameters was made. Experimental data were fitted to Langmuir, Freundlich, and Redlich-Peterson isotherm equations...
In this study, nitrate reduction using laboratory synthesized nanoscale zero-valent iron (NZVI) was discussed. On the other side, denitrification of nitrate with Fe0 nanoparticles combined with zeolite was also investigated. The effects of iron-to-nitrate ratio and the affiliation of zeolite were studied systemically. The results show that nitrate with the concentration of 80 mg/L was mostly removed...
