The Walkley-Black method using Ferrous Ammonium Sulfate -Potassium dichromate method was employed for the redox reaction. Back titration was carried out. Finding the amount of dichromate used, the ...

Visual titration is an important method for detecting the main and minor components in the samples. In visual titration, the image features are easily affected by the dichroism of the indicator, ...

Background and aims Manual laboratory continuous positive airway pressure (CPAP) titration for obstructive sleep apnoea (OSA) is costly, time intensive and delays access to treatment. Automatic ...

A new methodology is presented, called differential potentiometric titration (DPT), which allows the determination of the point of zero charge (pzc) of metal (hydr)oxides using only one potentiometric ...

Inhibitors of the renin–angiotensin–aldosterone (RAAS) system are cornerstones of the management of patients with heart failure with reduced left ventricular ejection fraction (HFrEF). However, RAAS ...

Objective To compare the analgesic efficacy of two techniques of morphine titration (intermittent intravenous bolus vs infusion) by calculating rescue dosage in a day at 1 week after analgesic ...

Isothermal titration calorimetry is increasingly becoming a common tool for the investigation of surfactant association processes. This can be associated with the development of new, sensitive and ...

Dichromate is a widespread contaminant in wastewater, threatening the health of humans and other organisms. Therefore, effective detection and removal of dichromate from water is of great significance ...

Samples of the solution (5 cm³) were withdrawn from the tank at 5 minute intervals for dichromate analysis by titration against standard solution of ferrous ammonium sulfate using diphenyl amine ...

This book covers both fundamental and practical aspects of chemical analysis: Data Process and Analysis; Chemical Equilibria and Volumetric titrations; Gravimetry; Spectrophotometry; Sample ...
