ʻO ka chlorine disinfectant ka mea maʻamau i hoʻohana ʻia a hoʻohana nui ʻia i ke kaʻina hana disinfection o ka wai paipu, nā loko ʻauʻau, nā papa ʻaina, a me nā mea ʻē aʻe. ʻO ka disinfection chlorination ua hoʻonui nui ʻia ka nānā. He hōʻailona koʻikoʻi ke koena o ka chlorine no ka loiloi ʻana i ka pono o ka disinfection wai.
I mea e pale aku ai i ka repopulation o ke koena bacteria, viruses a me na microorganisms i loko o ka wai, ma hope o ka holoi 'ia o ka wai me ka chlorine-containing disinfectants no kekahi manawa, pono e loa'a ka nui o ke koena chlorine i loko o ka wai no ka ho'omau 'ana. hiki i ka sterilization. Eia nō naʻe, ke kiʻekiʻe loa ke koena o ka chlorine content, hiki iā ia ke hoʻohaumia i ka lua o ka maikaʻi o ka wai, alakaʻi pinepine i ka hana ʻana i nā carcinogens, hoʻoulu i ka anemia hemolytic, a me nā mea ʻē aʻe, he mau hopena maikaʻi ʻole i ke olakino kanaka. No laila, he mea koʻikoʻi ka mālama pono ʻana a me ka ʻike ʻana i ke koena o ka chlorine i ka mālama wai.
Nui nā ʻano chlorine i loko o ka wai:
ʻO ke koena chlorine (klorine manuahi): Chlorine ma ke ʻano o ka hypochlorous acid, hypochlorite, a i ʻole ka chlorine elemental dissolved.
ʻO ka chlorine hui pū: Chlorine ma ke ʻano o nā chloramines a me nā organochloramines.
Ka nui o ka chlorine: Loaʻa ka chlorine ma ke ʻano o ke koena chlorine manuahi a i ʻole chlorine hui ʻia a i ʻole nā mea ʻelua.
No ka hoʻoholo ʻana i ke koena chlorine a me ka nui o ka chlorine i loko o ka wai, ua hoʻohana nui ʻia ke ʻano o-toluidine a me ke ʻano iodine i ka wā ma mua. He paʻakikī kēia mau ʻano hana a loaʻa nā pōʻai loiloi lōʻihi (koi i nā ʻenehana loea), a ʻaʻole hiki ke hoʻokō i nā koi no ka hoʻāʻo wikiwiki a me ke koi ʻana i ka maikaʻi o ka wai. nā koi a ʻaʻole kūpono no ka nānā ʻana ma ka pūnaewele; Eia kekahi, no ka mea, he carcinogenic ka o-toluidine reagent, ke koena o ka chlorine detection method in the "Hygienic Standards for Drinking Water" i hoolahaia e ke Kuhina Ola o ka People's Republic of Kina i Iune 2001 ua wehe i ka o-toluidine reagent. Ua hoʻololi ʻia ke ʻano benzidine e DPD spectrophotometry.
ʻO ke ala DPD i kēia manawa kekahi o nā ala pololei loa no ka ʻike koke ʻana i ke koena chlorine. Hoʻohālikelike ʻia me ke ʻano OTO no ka ʻike ʻana i ke koena chlorine, ʻoi aku ka kiʻekiʻe o kona pololei.
ʻO ka ʻike kiʻi kiʻi ʻokoʻa DPD ʻO ka Photometry kahi ʻano kemika analytical i hoʻohana mau ʻia e ana i ka neʻe ʻana o ke koena chlorine haʻahaʻa haʻahaʻa a i ʻole ka chlorine holoʻokoʻa i nā laʻana wai. Hoʻoholo kēia ʻano hana i ka neʻe ʻana o ka chlorine ma ke ana ʻana i ke kala i hana ʻia e kekahi hopena kemika.
ʻO nā kumu kumu o ka photometry DPD penei:
1. Pane: I loko o nā la'ana wai, ke koena chlorine a i'ole ka nui o ka chlorine e ho'opili me nā mea ho'opa'a kemika kūikawā (DPD reagents). Ke hoʻololi nei ke kala o ka hāʻina.
2. Hoʻololi kala: ʻO ka hui i hana ʻia e ka DPD reagent a me ka chlorine e hoʻololi i ke kala o ka hāpana hāpana wai mai ka waihoʻoluʻu ʻole a i ʻole melemele māmā i ʻulaʻula a poni paha. Aia kēia hoʻololi kala i loko o ka laulā spectrum i ʻike ʻia.
3. Ana kiʻi kiʻi: E hoʻohana i ka spectrophotometer a i ʻole kiʻi kiʻi kiʻi e ana i ka hoʻopaʻa ʻana a i ʻole ka lawe ʻana o kahi hopena. Hana ʻia kēia ana ma kahi lōʻihi nalu kikoʻī (maʻamau 520nm a i ʻole kekahi lōʻihi nalu kikoʻī).
4. Ka nānā 'ana a me ka helu 'ana: Ma muli o ke ana 'ana i ka absorbance a i 'ole ka waiwai transmittance, e ho'ohana i ke ka'e ma'amau a i 'ole ke kumu ho'omāka'ika'i no ka ho'oholo 'ana i ka ne'e o ka chlorine i ka hāpana wai.
Hoʻohana pinepine ʻia ka DPD photometry i ka ʻoihana mālama wai, ʻoi aku ka nui o ka hoʻāʻo ʻana i ka wai inu, ka maikaʻi o ka wai ʻauʻau a me nā kaʻina hana mālama wai. He ala maʻalahi a pololei ia e hiki ke ana koke i ka ʻike o ka chlorine e hōʻoia i ka ʻike ʻana o ka chlorine i loko o ka wai i loko o ka palena kūpono e hoʻopau ai i ka bacteria a me nā microorganism ʻino ʻē aʻe.
E ʻoluʻolu e ʻoluʻolu e ʻokoʻa nā ʻano loiloi kikoʻī a me nā mea hana ma waena o nā mea hana a me nā laboratories, no laila ke hoʻohana ʻana i ka photometry DPD, e ʻoluʻolu e nānā i ke ʻano analytical kikoʻī a me ka manual hana hana e hōʻoia i ka pololei a me ka hana hou.
ʻO ka LH-P3CLO i kēia manawa i hāʻawi ʻia e Lianhua he mita chlorine koena lawe ʻia e pili ana i ke ʻano photometric DPD.
Kūlike me ke kūlana o ka ʻoihana: HJ586-2010 Wai Wai - Ka Hoʻoholo ʻana i ka Chlorine Free a me ka Chlorine Total - N, N-diethyl-1,4-phenylenediamine spectrophotometric method.
Nā hana hoʻāʻo maʻamau no ka wai inu - Nā hōʻailona disinfectant (GB/T5750,11-2006)
Nā hiʻohiʻona
1, Maʻalahi a maʻalahi, kūpono i ka hālāwai ʻana i nā pono, ʻike wikiwiki i nā ʻano hōʻailona like ʻole a me ka hana maʻalahi.
2, 3.5-ʻīniha kala kala, maʻemaʻe a nani hoʻi, ke kaila kaila mea hoʻohana, ʻo ka nānā ʻana ke heluhelu pololei.
3, ʻEkolu mau hōʻailona hiki ke ʻike ʻia, e kākoʻo ana i ke koena chlorine, ka nui o ke koena chlorine, a me ka ʻike hōʻailona chlorine dioxide.
4, 15 pcs o nā pihi i kūkulu ʻia, kākoʻo i ka calibration curve, e hoʻokō i nā koi o nā keʻena noiʻi ʻepekema, a me ka hoʻololi ʻana i nā ʻano hoʻokolohua like ʻole.
5, Ke kākoʻo nei i ka calibration optical, e hōʻoia ana i ka ikaika o ka luminous, hoʻomaikaʻi i ka pololei o ka mea kani a me ka paʻa, a hoʻonui i ke ola lawelawe.
6, kūkulu ʻia ma ke ana ʻana i ka palena kiʻekiʻe, hōʻike intuitive o ka palena nui, ke kelepona e hōʻike ana i ka ʻike ʻana i ka waiwai palena kiʻekiʻe, ʻulaʻula wikiwiki no ka palena nui.
