Tikuchita khama kuti tikwaniritse vutoli ndipo tikukulandirani moona mtima kuti mudzatilembetse!
Sitidzangoyesetsa kukupatsani ntchito zabwino kwambiri kwa kasitomala aliyense, komanso tili okonzeka kulandira malingaliro aliwonse omwe ogula athu amapereka. Pakadali pano katundu wathu watumizidwa kum'mawa kwa Europe, Middle East, Southeast, Africa ndi South America ndi zina zotero. Takhala ndi zaka 13 tikugulitsa ndi kugula zida za Isuzu kunyumba ndi kunja komanso tili ndi makina owunikira zida zamagetsi a Isuzu. Timalemekeza mfundo yathu yayikulu ya Kuona Mtima mu bizinesi, kuyika patsogolo ntchito ndipo tidzachita zonse zomwe tingathe kuti tipatse makasitomala athu katundu wapamwamba komanso ntchito yabwino kwambiri.
3. Kuchotsa
Yesani 5.0 g ya chitsanzocho mu beaker ya 100 mL.
Onjezani 20 mL ya madzi ndi 0.5 mL ya yankho la phosphoric acid la 1.0 mol/L.
Chitani kuchotsa kwa ultrasound kwa mphindi 10.
Sinthani pH kufika pa 3.0 pogwiritsa ntchito yankho la phosphoric acid la 1.0 mol/L.
Ikani chisakanizocho mu botolo la 50 mL, sakanizani ndi madzi mpaka chizindikirocho chifike, ndipo sakanizani bwino.
Tumizani chitsanzo chonsecho ku chubu cha pulasitiki cha 50 mL, chiyimitseni kwa mphindi 5, kenako chiyimitseni pa liwiro la 8000 rpm kwa mphindi 5.
Sonkhanitsani 5 mL ya supernatant kuti muyeretsedwe.
