Obere ihe ọmụma na nnukwu ihe ọmụma ︨ Nkuzi nhazi ihe atụ phosphorus zuru oke

Ịhazi ihe nlele ọkọlọtọ bụ ihe a na-eme ugboro ugboro n'oge nnwale. Site n'iji nnwale metụtara nnwale ihe ngosi mma mmiri dịka ihe atụ, site n'ịhazi ihe nlele ọkọlọtọ, site n'ịtụnyere uru a tụrụ na uru ntụaka nke ihe nlele ọkọlọtọ, mmadụ nwere ike ikpebi ma njehie nke ngwa nnwale ahụ dị n'ime oke akọwapụtara, ebe onye nke ọzọ nwere ike ịchọpụta ma usoro nha nke onye nnwale ahụ ziri ezi. Ya mere, ịhazi ihe nlele ọkọlọtọ dị oke mkpa maka ntụkwasị obi nke nnwale ahụ.
Ihe ndị a ga-egosi usoro nhazi nke mkpokọta ihe nlele ọkọlọtọ phosphorus, bịa lee anya.
Nzọụkwụ mbụ bụ ịkwadebe ihe oriri pụrụ iche nke Lianhua Technology maka phosphorus-potassium dihydrogen phosphate (KH2PO4), mmiri a gwakọtara agwakọta, beaker, mkpanaka na-akpali akpali, na 1000mL volumetric flask tupu nhazi ya.
Nzọụkwụ nke abụọ bụ ịwere obere potassium dihydrogen phosphate (KH2PO4) wee kpọọ ya nkụ na 110℃ ruo awa abụọ, wee wepụ ya mgbe ọ jụrụ oyi.
Nzọụkwụ nke atọ bụ ịtụ 0.2197 g nke potassium dihydrogen phosphate kpọrọ nkụ (KH2PO4) nke ọma ma tinye ya n'ime beaker, tinye ihe dị ka 100 ml nke mmiri a gwakọtara agwakọta, gwakọta ya ruo mgbe ọ ga-agbaze kpamkpam, wee tinye 5 mL nke sulfuric acid nke a na-enyocha, wee bufee ya na volumetric flask (enwere ike ịsacha beaker ahụ ugboro atọ na mmiri a gwakọtara agwakọta, a na-etinyekwa mmiri ịsacha ahụ na volumetric flask), wee mechaa gwakọta ya ruo 1000 mL.
Ugbua, ihe nlele phosphorus zuru oke nke 50 mg/L dị njikere. Enwere ike iji ihe nlele ọkọlọtọ akwadoro nwalee ma dozie ngwaọrụ, oge nchekwa ya na-abụkarị ọnwa isii.
Nke dị n'elu bụ usoro nhazi nke ihe nlele phosphorus zuru oke na mbipụta a. Soro m ka ịmatakwu ihe ọmụma nnwale!
