Ka helu ʻana o ke ʻano decolorizing agent (e lawe ana i kahi hoʻokolohua kikoʻī ma ke ʻano he laʻana)

1. Ka helu o ka reagent (PPM) = [(helu helu /20) × ka hoʻoheheʻe ʻana o ka wai hoʻoheheʻe / ka nui o ka wai hoʻāʻo] ×106

★ ʻO ka PPM hoʻokahi hapa o ka miliona, a ʻo ka helu ʻana he 1PPM, ʻo ia ka like me ka 1 tona o ka wai ʻino, ʻo ka nui o ka mea hana he 1 gram.

★ 1ML diluted solution ua like ia me 20 kulu

2. E hoʻohana i ka beaker e lawe i 200ML o ka wai hoʻāʻo (chroma 200, COD 110), hoʻololi i ka waiwai PH i 8, e hoʻohui i 10 kulu o ka wai.mea hoopau kalahoʻonā me ka eyedropper (1ML ua like me 20 kulu), hoʻoulu, a laila hoʻohui i 12 kulu o PAC, hoʻoulu, a hope e hoʻohui i 2 kulu o PAM, hoʻoulu, a kū no hoʻokahi minuke. ʻO ka chroma ʻike ʻia ʻo 4 (dilution multiple method) a ʻo COD ka 85, e kū ana i ke kūlana hoʻokuʻu aupuni.

3. ʻO ke ʻano o ka hoʻomākaukau ʻana i ka reagent:mea hoopau kala(2% solution, ʻo ia hoʻi, dilution 50 manawa), PAC (2% solution), PAM(1‰ aqueous solution)

Ka nui omea hoopau kala= [(10/20) ×2%/200] ×106 = 50PPM

ʻAha PAC = [(12/20) ×2%/200] ×106 = 60PPM

Ka nui o PAM = [(2/20) ×1‰/200] ×106 = 0.5PPM

Ka nui omea hoopau kalahe 50PPM, ua like ia me 50 grams o kamea hoopau kalaʻO ka hopena waiwai i loko o hoʻokahi tona o ka wai ʻino, a pēlā aku, ʻo PAC he 60 kalama, a ʻo PAM he 0.5 kalama.
