Total hardness was assessed via EDTA titration (APHA Method 2340 C). Calcium was analyzed using APHA Method 3500-Ca B with Calcon-Carboxylic acid as the indicator, and magnesium was determined using ...

Figure 5 Calcium oxide content (wt.%) of the filtrate (leaching liquor) when using HCl and CH 3 COOH for leaching, with different molar concentrations, according to the EDTA titration method ...

Lower concentrations of EDTA and EGTA were found to be more effective than CDTA; 1% EDTA and 1% EGTA had similar demineralisation effect on dentin. Citric acid at neutral pH did not significantly ...
