Uburyo bwo kugerageza kongeramo ibintu bidafite umwimerere mu bikoresho bifasha mu gutunganya ACR:

Uburyo bwo gutahura Ca2+:

Ibikoresho byo kugerageza n'ibikoreshwa mu gukora: icupa ry'inkono; Icupa rifite ishusho y'agace k'umuhondo; Ifuru; burette; Ifuru y'amashanyarazi; Etanoli y'amazi; Aside Hydrochloric, umuti wa NH3-NH4Cl wa buffer, ikimenyetso cya kalisiyumu, umuti usanzwe wa 0.02mol/L EDTA.

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 iyuni za kalisiyumu zihuze neza na aside hydrochloric;

2. Karaba n'amazi hanyuma uyungurure unyuze mu muyoboro kugira ngo ubone amazi meza;

3. Hindura agaciro ka pH karenze 12 ukoresheje umuti wa NH3-NH4Cl buffer, ongeramo ingano ikwiye ya calcium indicator, hanyuma ushyiremo umuti usanzwe wa 0.02mol/L EDTA. Iherezo ni igihe ibara rihinduka kuva ku mutuku w'umuhengeri rijya ku bururu bw'ubururu;

4. Gukora igerageza ryimbitse icyarimwe;

5. Kubara C # a2+=0.02 $(V-V0) $0.04004M $%&&

V - Ingano (mL) y'umuti wa EDTA wakoreshejwe mu gupima ingero z'ubufasha mu gutunganya ACR.

V # – Ingano y'umuti wakoreshejwe mu gihe cy'igerageza ridafite ikintu

M - Gupima uburemere (g) bw'icyitegererezo cy'ubufasha mu gutunganya ACR.

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 ukuri kugeza kuri 0.001g), uzishyire mu itanura rifunze ubushyuhe 950 mu gihe cy'isaha 1, ukonje, hanyuma upime kugira ngo ubare ibisigazwa bisigaye byatwitswe. Iyo ibintu bidafite umwimerere byongewe mu ngero za ACR, hazabaho ibisigazwa byinshi.
