Iyo Chemistry yeH2S Mitigation. Isu tinokoshesa zvinhu zvitatu zvakakosha zveH2S molecule panguva yeH2S kuderedza.
H2S igasi rine acidic uye ichaita munyu maamine akawanda kune aminium hydrosulphide. Mhedzisiro yacho inodzoserwa kumashure uye inoumba hwaro hwechikamu chekudzokorodza amine; munyu uri kuparadzaniswa kudzokera kuH2S uye yemahara amine nekupisa. Iyi nzira inobvisawo CO2 sezvo iriwo gasi rine acidic.
H2S inoderedza mumiririri uye nekudaro inogona kuve nyore oxidized. Iyo valence mamiriro esarufa ndeye -2 muH2S uye inogona kuve oxidized kusvika ku0, elemental sulfur (eg alkaline sodium nitrite kana hydrogen peroxide) kana +6, sulphate nechlorine dioxide, hypohalites nezvimwe.
H2S ine nucleophile ine simba nekuda kwesarufa atomu inova yakapfava Lewis base. Maerekitironi ari mugoko remaerekitironi matatu, kure kure kubva kunucleus, anofambisa uye anotamiswa zviri nyore. Muenzaniso wakakwana weizvi inyaya yekuti H2O imvura ine nzvimbo yekuvira ye100 C nepo H2S, molekuru inorema, igasi rine poindi yekuvira -60 C. The hard Lewis basic property yeatomu yeokisijeni inoumba hydrogen yakasimba kwazvo. zvisungo, zvakanyanya kupfuura H2S, saka mutsauko mukuru wekubikira. Iyo nucleophilic inogona yeatomu yesarufa inoshandiswa mukuita ne triazine, formaldehyde uye hemiformal kana formaldehyde releasers, acrolein uye glyoxal.
