AB  - Green chemistry has emerged as a significant field in science in recent years due to
environmental concerns, the need to mitigate chemicals health hazards, regulatory
pressure, and economic benefits. This paper analyzes the trend of scientific publications on
green chemistry in Serbia over the last 10 years. For this purpose, data were retrieved from
the Scopus through a search for the study period, 2014-2024, limited to Serbia. In total, 96
records were retrieved. The results showed that green chemistry is increasingly prevalent
in different fields of knowledge in Serbia, with the highest percentages in chemistry
(22.1%), biochemistry, genetics, and molecular biology (19.1%), environmental science
(13.6%), The number of publications first peaked in 2018, decreasing in subsequent years
probably due to the COVID-19 pandemic, and then peaking again even more in 2022.
Concerning the type of publication, most publications are Articles (90.6%) and Reviews
(7.3%), with more than half affiliated with the University of Belgrade (56 documents). The
obtained results indicate that the green chemistry in Serbia is becoming more recognizable
among researchers in recent years, and it can be assumed that this interest will continue to
trend upwards.

AB  - In chemical processes it is of essential for flow in the process to be accurate and well defined. 
Fluid velocity measurements are important for fluid flow quality performance in the systems. 
This study focuses on determination of volumetric flow rate measurement and on calibration 
of conventional flowmeter using industrial radiotracer approach. In this work, the application 
of radiotracer method for RTD measurement in flow meter calibration for chemical industry 
is described. The experiments in pilot-scale flow rig were performed using Technetium-99 m 
(
99mTc) as a radiotracer in the form of pertechnetate ion (99mTcO4
-
) to calibrate flow meter. The 
data were evaluated using plug flow with axial dispersion model of RTD software.
The optimization of the parameters included input signal of radiotracer, concentration of 
radiotracer and position of detectors. The measured data were analyzed, and precision of 
experimental setup was investigated under two different approaches. A plug flow with axial 
dispersion was used to simulate the measured RTD curves and investigate flow dynamics of 
the flowing water. The results of the study, showed that there might be an optimum injection 
volume range of the tracer for each specific application.
The optimum range in this study was determined from 300 to 700 µL. In this range, relative 
standard deviation was around 1% for both calculation methods, which is lower than with 
other available injection volumes. Bias of the initial flow rate was lower using summation 
approximation, resulting in ca 9% in the area of interest. In case of RTD software, bias values 
were between 10 and 11%. For the first time the variation of standard deviation of calculated 
flow rate with injection volume and activity of radiotracer was determined. The results of the 
study may help in injection volume optimization as well as give a guide on how to process 
data without RTD software, as the results obtained by both methods were in great agreement. 
They also revealed a slight dependency of the precision of output results on the injection 
volume as well as similar results for manual and specialized RTD software data processing. The 
study that investigated the change of standard deviation of calculated flow rate with injection 
volume and activity of used radiotracer was conducted for the first time in literature.

This study focuses on determination of the volumetric flow rate and its standard (relative) deviation for calibration of conventional flow meters by using a radiotracer approach. The measurements for flow meter calibration were performed at a pilot-scale flow rig using Technetium-99 m (99mTc) as a radiotracer in the form of pertechnetate ion (99mTcO4-). The measured data were analyzed, and precision of the experimental setup was investigated under two different approaches – IAEA’s RTD software and sum approximation of raw data. For the first time, the variation of standard deviation of calculated flow rate with the injection volume and activity of the radiotracer was determined. Plug flow with axial dispersion was used to simulate the measured RTD curves and investigate the flow dynamics of the flowing water. The results of the study have shown the possibility of in situ calibration of flow meters with a relative error lower than 1 %. They also revealed a slight dependency of the precision of output results on the injection volume as well as similar results for manual and specialized RTD software data processing.
