Study of chlorinated ethylenes remediation by non stabilized and Si-stabilized nanoiron.
Original language description
This study deals with the ability of nanoscale zero-valent iron particles (NZVI) to decompose chlorinated ethylenes. Chlorinated ethylenes are common contaminants found on many sites in the Czech Republic. The application of NZVI suspension is a very useful technique for cleaning up these sites. In the study, batch experiments were performed to simulate an in situ chemical reduction remediation technology. We studied interaction of aqueous suspension of nanoiron particles RNIP-10APS (TODA Kogyo Corp.) with tetrachlorethylene (PCE) and trichloroethylene (TCE). In the original NZVI suspension, the particles agglomerate quickly after preparation. Therefore, we proposed an environmental friendly and cost effective method of NZVI stabilization by silicate stabilizing agent. This method prevents the particles from aging and agglomerating. The main goal was to compare the ability of the original NZVI and the Si-stabilized NZVI to decompose selected contaminants. The used stabilizing Si-agent
