Phytoremediation ea Mobu o Silafetseng ka Metal Ho Sebelisa Lihlomathiso tsa Organic

Acated carbon e na le lintho tse nang le carbonaceous tse nkiloeng mashala. Khabone e kentsoeng e hlahisoa ke pyrolysis ea lihlahisoa tsa tlhaho tsa semela. Lisebelisoa tsena li kenyelletsa mashala, likhetla tsa coconut le patsi,mokotla oa 'moba,makhapetla a soyale ka bokhutšoanyane (Dias et al., 2007; Paraskeva et al., 2008). Ka tekanyo e fokolang,mantle a phoofololi boetse li sebelisoa bakeng sa tlhahiso ea activated carbon. Tšebeliso ea carbon activated e tloaelehile ho tlosa litšepe metsing a litšila, empa tšebeliso ea eona bakeng sa ho thibela tšepe ha e tloaelehe mobung o silafetseng (Gerçel le Gerçel, 2007; Lima le Marshall, 2005b). Manyolo a likhoho a nkiloeng k'habone e ne e e-na le bokhoni bo botle ba tšepe e tlamang (Lima le Marshall, 2005a). Khabone e kentsoeng hangata e sebelisoa bakeng sa ho lokisa litšila tse mobung le metsing ka lebaka la sebopeho sa porous, sebaka se seholo sa holim'a metsi le matla a phahameng a adsorption (Üçer et al., 2006). Khabone e kentsoeng e tlosa litšepe (Ni, Cu, Fe, Co, Cr) ho tsoa tharollong ka pula e kang metal hydroxide, adsorption on activated carbon (Lyubchik et al., 2004). Lekhapetla la almond le nkiloeng ka AC le tlositse Ni ho tsoa metsing a litšila ka ntle le H₂SO₄kalafo (Hasar, 2003).

Haufinyane tjena, biochar e 'nile ea sebelisoa e le phetoho ea mobu ka lebaka la liphello tsa eona tse molemo mobung o fapaneng oa' mele le lik'hemik'hale (Beesley et al., 2010). Biochar e na le litaba tse phahameng haholo (ho fihla ho 90%) ho latela lisebelisoa tsa motsoali (Chan le Xu, 2009). Keketso ea biochar e ntlafatsa ho ata ha carbon e qhibilihisitsoeng,mobu pH, e fokotsa litšepe ka har'a leachate le ho tlatsetsa limatlafatsi tse kholo (Novak et al., 2009; Pietikäinen et al., 2000). Ho phehella ha nako e telele ha biochar mobung ho fokotsa ho kenngoa ha litšepe ka ho sebelisoa khafetsa ha liphetoho tse ling (Lehmann le Joseph, 2009). Beesley et al. (2010) o ile a etsa qeto ea hore biochar e fokolitse Cd le Zn tse qhibilihang ka metsi mobung ka lebaka la ho eketseha ha carbon le pH. Khabone e fokotsehileng methapo ea tšepe (Ni, Cu, Mn, Zn) letlobong la limela tsa poone tse lenngoeng mobung o silafetseng ha ho bapisoa le mobu o sa lokisoang (Sabir et al., 2013). Biochar e fokolitse likhahla tse phahameng tsa Cd le Zn tse qhibilihang mobung o silafetseng (Beesley le Marmiroli, 2011). Ba fihletse qeto ea hore sorption ke mokhoa oa bohlokoa oa ho boloka litšepe ke mobu. Biochar e fokolitse khatello ea maikutlo ea Cd le Zn ho fokotseha ha 300- le 45 ka makhetlo a bona a leachate, ka ho latellana (Beesley le Marmiroli, 2011).
