Abstract

Inventia se refera la procedee de modificare a structurii poroase a carbunilor activi impregnati cu Cu(II) si la utilizarea acestora pentru purificarea prin oxidare catalitica a apelor subterane de hidrogen sulfurat si sulfuri.Procedeul de modificare a structurii poroase a carbunelui activ impregnat cu Cu(II) include malaxarea mecanica timp de o ora la temperatura camerei a unei suspensii de adsorbant în apa demineralizata cu barbotarea concomitenta a oxigenului. Ca rezultat se micsoreaza suprafata specifica si volumul microporilor adsorbantului.Procedeul de purificare a apelor subterane de hidrogen sulfurat si sulfuri prin oxidare catalitica include adaugarea în apa subterana a carbunelui activ impregnat cu Cu(II), cu structura poroasa modificata conform procedeului sus-mentionat, malaxarea mecanica a suspensiei carbune-apa, timp de o ora la temperatura camerei cu barbotarea concomitenta a oxigenului, dupa care se separa carbunele activ de apa purificata pentru o eventuala reutilizare într-un nou ciclu de purificare.Utilizarea adsorbantului cu structura poroasa astfel modificata exclude formarea sulfului pe suprafata lui, ce indica asupra sporirii activitatii catalitice a unui astfel de adsorbant.
