Ho hlophisa disampole tse tloaelehileng ke ntho e hlokang ho etsoa khafetsa nakong ea liteko. Ha re nka teko e amanang le matšoao a boleng ba metsi a teko e le mohlala, ka ho hlophisa disampole tse tloaelehileng, ka ho bapisa boleng bo lekantsoeng le boleng ba referense ea sampole e tloaelehileng, motho a ka fumana hore na phoso ea sesebelisoa sa teko e ka har'a moeli o boletsoeng, 'me e mong a ka netefatsa hore na mokhoa oa ho lekanya oa motho ea lekang o nepahetse. Ka hona, ho hlophisa disampole tse tloaelehileng ho bohlokoa haholo ho ts'epahalong ea teko.
Tse latelang li tla hlahisa mokhoa oa ho hlophisa sampole e tloaelehileng ea phosphorus kaofela, tloo u shebe.
Mohato oa pele ke ho lokisa lintho tse khethehileng tse sebelisoang ke Lianhua Technology bakeng sa phosphorus-potassium dihydrogen phosphate (KH2PO4), metsi a hloekisitsoeng, beaker, molamu o hlohlelletsang, le flask ea volumetric ea 1000mL pele ho tlhophiso.
Mohato oa bobeli ke ho nka potassium dihydrogen phosphate e nyane (KH2PO4) ebe o e omisa mochesong oa 110℃ ka lihora tse 2, ebe o e ntša ka mor'a ho e pholile.
Mohato oa boraro ke ho lekanya ka nepo 0.2197 g ea potassium dihydrogen phosphate (KH2PO4) e omisitsoeng ebe u e kenya ka har'a beaker, eketsa hoo e ka bang 100 ml ea metsi a hloekisitsoeng, u hlohlelletse ho fihlela e qhibiliha ka botlalo, ebe u eketsa 5 mL ea analytical grade sulfuric acid, ebe u e fetisetsa ka har'a beaker ea volumetric (beaker e ka hlatsuoa ka makhetlo a mararo ka metsi a hloekisitsoeng, 'me tharollo ea ho hlatsoa le eona e eketsoa ka har'a beaker ea volumetric), 'me qetellong e hlapolloe ho fihlela ho 1000 mL.
Jwale, sampole e tloaelehileng ya phosphorus ya 50 mg/L e se e loketse. Sampole e tloaelehileng e lokisitsweng e ka sebediswa ho leka le ho lekanya disebediswa, mme nako ya ho boloka disebediswa hangata ke dikgwedi tse 6.
Mokhoa o ka holimo ke oa ho hlophisa sampole e tloaelehileng ea phosphorus tokollong ena. Ntatele ho ithuta tsebo e eketsehileng ea liteko!
