Combined respirometric – titrimetric data are presented, resulting from aerobic batch degradation experiments in activated sludge with acetate and dextrose as a substrate. A model including substrate uptake, CO2 production and NH3 uptake for biomass growth is proposed to describe the titrimetric data. Combining respirometric and titrimetric data is more informative compared to the separate data...

The development of titrimetric sensor applications to monitor biological wastewater treatment processes is shortly described, and the measurement principle (based on a pH controller) is illustrated. 3 applications that were developed during the past years are used to illustrate the capabilities of titrimetric sensors. The ammonium and the nitrate concentration can be measured to monitor the nit...

was outlined in detail, with gasometric measurement of the iodate resulting from the reaction. In this paper titrimetric measurement of the iodate is described. Titrimetric measurement of the iodate is directly applicable to the supernatant fluid in the AgI08 precipitation of chloride from salt solutions, urine, serum, and protein-free jiltrate of serum and of whole blood.’ For the titrimetric ...

This paper describes the Spectrophotometric and titrimetric methods for the determination of gentamycin and amoxycillin. The use of potassium iodate reagent for direct titrimetric method for the determination of some selected antibiotic has been described. The end point was characterized by a sharp change in color from colorless to deep red followed by spectrophotometric measurements.

A semi-automated method for the determination of free fatty acids in plasma based on Mosinger's manual method (Mosinger, 1965) is described and the results of a comparison with Dole's titrimetric method (Dole, 1956) are presented. There is almost perfect correlation between the two methods, and the automated technique is simple, reliable, and significantly more accurate and precise than the tit...

Ethambutol tablets of 200 and 400 mg denominations were assayed by the standard non-aqueous titration method and a simpler calorimetric method. With the titrimetric method, assay values, appreciably higher than the stated content (117% or more), were obtained with the products of 4 companies, while all the values were within 6% of the stated content by the calorimetric method. Rifampicin and py...

Titrimetric methods are considered to be useful for the study of biological wastewater treatment processes, particularly those processes that have negligible influence on the dissolved inorganic carbon pool. However, the application of titrimetric methods for studying biological processes that produce/consume carbon dioxide is not straightforward as microbial activity affects the total amount o...
