Titration with Adsorption Indicator. V

Determination of polyhexamethylene biguanide hydrochloride using photometric colloidal titration with crystal violet as a color indicator.

A solution of polyhexamethylene biguanide hydrochloride (PHMB-HCl) was titrated with a standard solution of potassium poly(vinyl sulfate) (PVSK) using crystal violet (CV) as an photometric indicator cation. The end point was detected by a sharp absorbance change due to an abrupt decrease in the concentration of CV. A linear relationship between the concentration of PHMB-HCl and the end-point vo...

Ultramicro- and micro-determination of chloride by argentimetric titration with the indicator dichlorofluorescein.

A reliable ultramicro modification of the Franco and Klein (1) determination for chloride, using 20 pi. of plasma, is described. A second procedure, requiring 0.2 ml. of plasma and substituting a titrating syringe for a buret, is suggested as a fast and adequate substitute in the absence of either extensive laboratory facilities or trained personnel. Data on reproducibility and recovery, and a ...
