Abstract
Invenţia se referă la procedee de modificare a structurii poroase a cărbunilor activi impregnaţi cu Cu(II) şi la utilizarea acestora pentru purificarea prin oxidare catalitică a apelor subterane de hidrogen sulfurat şi sulfuri.Procedeul de modificare a structurii poroase a cărbunelui activ impregnat cu Cu(II) include malaxarea mecanică timp de o oră la temperatura camerei a unei suspensii de adsorbant în apă demineralizată cu barbotarea concomitentă a oxigenului. Ca rezultat se micşorează suprafaţa specifică şi volumul microporilor adsorbantului.Procedeul de purificare a apelor subterane de hidrogen sulfurat şi sulfuri prin oxidare catalitică include adăugarea în apa subterană a cărbunelui activ impregnat cu Cu(II), cu structura poroasă modificată conform procedeului sus-menţionat, malaxarea mecanică a suspensiei cărbune-apă, timp de o oră la temperatura camerei cu barbotarea concomitentă a oxigenului, după care se separă cărbunele activ de apa purificată pentru o eventuală reutilizare într-un nou ciclu de purificare.Utilizarea adsorbantului cu structura poroasă astfel modificată exclude formarea sulfului pe suprafaţa lui, ce indică asupra sporirii activităţii catalitice a unui astfel de adsorbant.
