Ni gute wagerageza kongeramo ibintu bidafite umwimerere mu bikoresho bifasha mu gutunganya ACR?

Uburyo bwo gutahura Ca2+:

Ibikoresho byo kugerageza n'ibikoreshwa mu gukora: amacupa y'amazi; Icupa ry'ibumba rinini; Ifuru; Burette; Ifuru y'amashanyarazi; Etanoli y'amazi; Aside Hydrochloric, umuti wa NH3-NH4Cl wa buffer, ikimenyetso cya kalisiyumu, umuti usanzwe wa 0.02mol/LEDTA.

Intambwe zo kugerageza:
1. Pima neza ingano runaka y'icyitegererezo cy'ubufasha mu gutunganya ACR (kingana na 0.0001g) hanyuma ugishyire mu gikombe. Utose ethanoli idafite amazi, hanyuma wongeremo aside hydrochloric irenze 1:1 hanyuma uyishyushye ku itanura ry'amashanyarazi kugira ngo iyoni za kalisiyumu zikore neza hamwe na aside hydrochloric;
2. Karaba n'amazi hanyuma uyungurure ukoresheje umuyoboro kugira ngo ubone amazi meza;
3. Hindura agaciro ka pH karenze 12 ukoresheje umuti wa NH3-NH4Cl, ongeramo ingano ikwiye ya calcium indicator, hanyuma ushyiremo umuti usanzwe wa 0.02mol/LEDTA. Iherezo ni igihe ibara rihinduka kuva ku mutuku w'umuhengeri rijya ku bururu bw'ubururu;
4. Kora ikizamini cy'ubusa icyarimwe;
5. Kubara C # a2+=0.02 $(V-V0) $0.04004M $%&&
V - Ingano y'umuti wa EDTA wakoreshejwe mu gupima ingero z'ubufasha bwo gutunganya ACR (mL).
V # - Ingano y'umuti wakoreshejwe mu igerageza ridafite ikintu
M — Pima uburemere bw'icyitegererezo cy'ubufasha mu gutunganya ACR (g).

Uburyo bwo gutwika ibintu bidashobora kubaho:
Ibikoresho byo kugerageza: kuringaniza isesengura, itanura rifunguye.
Intambwe zo gupima: Fata ingero za 0.5,1.0g z'ubufasha bwo gutunganya ACR (zifite ubuziranenge kugeza kuri 0.001g), uzishyire mu itanura rifunze ubushyuhe buhoraho bwa 950 hanyuma uzitwike isaha 1, hanyuma uzikonjeshe hanyuma uzipime kugira ngo ubare ibisigaye byatwitswe. Niba ibintu bidafite umwimerere byongewe ku rugero rw'ubufasha bwo gutunganya ACR, hazabaho ibisigazwa byinshi.
Uburyo bwo gushongesha:
1. Ibikoresho byo kugerageza n'uburyo bwo gusesengura reagents; icupa ry'amazi rya 25ml; Trichloromethane.
Intambwe ya 2: Dukurikije uburyo bwo gupima ubukana bwa ACR, pima 75mg y'icyitegererezo hanyuma ugishyire mu icupa rya 25ml. Ongeramo umuti wa trichloromethane. Niba hari ubushyuhe cyangwa urumuri rugaragara.
