Sensitized schiff's reagent as an acid-base indicator

Analytica Chimica Acta, 1954
Abstract The sensitized Schiff's reagent has been used as an indicator in the neutralization of strong acids by means of strong or weak bases. (1) Since the acid to alkali transition is much sharper than the reverse process, the titration is best done by adding alkali to the acid.

Ion-Selective Optode Nanospheres as Heterogeneous Indicator Reagents in Complexometric Titrations

Analytical Chemistry, 2015
Traditionally, optical titrations of inorganic ions are based on a rapid and visible color change at the end point with water-soluble organic dyes as indicators. Adequate selectivity is required for both the indicator and the complexing agent, which is often limited.

New methods for quantification of Fenton’s reagent addition based on aged sludge indicators to improve filterability

Journal of Hazardous Materials, 2021
Fenton oxidation can effectively improve the dewaterability of aged sludge. Quantification of the addition of optimal reagents is central to the conditioning and dewatering of aged sludge. Improving the accuracy of quantification is significant to promote cost effectiveness.

Preparation of reagent indicator papers with silver triangular nanoplates for chemical analysis

Moscow University Chemistry Bulletin, 2017
An impregnation method to prepare reagent indicator papers with silver triangular nanoplates (TNPs) is developed. The conditions for obtaining modified papers (type of paper, method for applying TNPs, and drying conditions) allowing for an acceptably uniform distribution of the TNPs are chosen. The spectral characteristics of the prepared materials are
