Iji Mgbanwe Organic Emezi Ala Ndị Metọrọ n'Ọla

Kabọn a na-arụ ọrụ nwere ihe na-emepụta kabọn nke sitere na unyi. A na-emepụta kabọn a na-arụ ọrụ site na pyrolysis nke ihe ndị sitere na osisi. Ihe ndị a gụnyere kol, shei aki oyibo na osisi,akpa shuga,akpụkpọ anụ soybeanna nkenke (Dias et al., 2007; Paraskeva et al., 2008). N'ọkwa dị oke,nri anụmanụA na-ejikwa ya eme ihe maka mmepụta nke carbon arụ ọrụ. Ojiji nke carbon arụ ọrụ bụ ihe a na-ahụkarị iji wepụ ọla na mmiri mkpofu, mana ojiji ya maka igbochi ígwè anaghị adịkarị na ala ruru unyi (Gerçel na Gerçel, 2007; Lima na Marshall, 2005b). Nsị anụ ọkụkọ sitere na carbon arụ ọrụ nwere ikike njikọ ígwè dị mma (Lima na Marshall, 2005a). A na-ejikarị carbon arụ ọrụ eme ihe maka idozi ihe ndị na-emerụ emerụ na ala na mmiri n'ihi nhazi oghere, nnukwu ebe elu na ikike nnabata dị elu (Üçer et al., 2006). Carbon arụ ọrụ na-ewepụ ọla (Ni, Cu, Fe, Co, Cr) site na ngwọta site na mmiri ozuzo dị ka metal hydroxide, adsorption na carbon arụ ọrụ (Lyubchik et al., 2004). Ac almond nke AC nwetara wepụrụ Ni nke ọma na mmiri mkpofu na na-enweghị H₂SO₄ọgwụgwọ (Hasar, 2003).

N'oge na-adịbeghị anya, ejirila biochar mee ihe dị ka ihe ndozi ala n'ihi uru ya na ihe onwunwe anụ ahụ na kemịkalụ dị iche iche nke ala (Beesley et al., 2010). Biochar nwere nnukwu ọdịnaya (ruo 90%) dabere na ihe ndị sitere na ya (Chan na Xu, 2009). Mgbakwunye biochar na-eme ka mmịpụta nke carbon organic agbaze mma,pH ala, na-ebelata ọla dị n'ime mmiri ma na-emeju ihe oriri macro (Novak et al., 2009; Pietikäinen et al., 2000). Ogologo oge nke biochar n'ime ala na-ebelata ntinye nke ọla site na iji mgbanwe ndị ọzọ ugboro ugboro (Lehmann na Joseph, 2009). Beesley et al. (2010) kwubiri na biochar belatara Cd na Zn mmiri na-agbaze n'ime ala n'ihi mmụba na carbon na pH organic. Carbon a na-arụ ọrụ belatara ntinye nke metal (Ni, Cu, Mn, Zn) na ome nke osisi ọka a kụrụ n'ala ruru unyi ma e jiri ya tụnyere ala a na-agbanwebeghị (Sabir et al., 2013). Biochar belatara oke mkpokọta nke Cd na Zn a na-agbaze n'ime ala ruru unyi (Beesley na Marmiroli, 2011). Ha kwubiri na sorption bụ usoro dị mkpa maka idobe ọla site na ala. Biochar belatara ọnụọgụgụ Cd na Zn ruo na mbelata okpukpu 300 na 45 na mkpokọta mmiri ha, n'otu n'otu (Beesley na Marmiroli, 2011).
