Remediation of environment contaminated by lead using synthetic and natural apatites / Stabilizacija zagađenja olovom korišćenjem sintetičkih i prirodnih apatita
(Association of the Chemical Engineers of Serbia, 2001)
Lead contamination is an environmental concern due to its effect on human health. One of the ways of remediating lead contamination is the in situ stabilization of this heavy metal. This can be achieved by converting ...
The analysis of different processes of extraction: yield of extracts obtained from Aloe vera (Aloe barbadensis Miller) and sweet bay (Laurus nobilis L.) and the exergy analysis of applied processes
(Association of the Chemical Engineers of Serbia, 2009)
The present study was aimed to investigate and compare the efficiency of different methods for the isolation extract from a plant material. Extracts from dried leaves of Aloe vera (A. barbadensis Mill.) and Sweet Bay (Laurus ...
Photocatalytic degradation of textile dye C.I. reactive orange 16 in TiO2 water suspension by simulated solar light
(Association of the Chemical Engineers of Serbia, 2007)
The photodegradation of C.I. Reactive Orange 16 (RO16), commonly used as a textile dye, was investigated using TiO2 as a catalyst and the sun lamp. The experiments showed that TiO2 and simulated solar light are necessary ...
Preparation and characterization of penicillin acylase immobilized on sepabeads EC-EP carrier
(Association of the Chemical Engineers of Serbia, 2007)
This paper reports the covalent immobilization of penicillin G acylase from E. coli on Sepabeads EC-EP, an epoxy-activated polymethacrylic carrier, and describes the properties of the immobilized enzyme. Due to its versatility ...
Photocatalytic degradation of textile dye CI Basic Yellow 28 in water by UV-A/TiO2
(Association of the Chemical Engineers of Serbia, 2007)
CI Basic Yellow 28 (BY28), commonly used as a textile dye, could be photocatalytically degraded using TiO2 as catalyst and irradiated by UV-A lamp (300 W). However, UV and TiO2 showed no effect on the photodegradation when ...
Cleaner metallurgical industry in Serbia: A road to the sustainable development
(Association of the Chemical Engineers of Serbia, 2009)
Since the sustainable development has been a global and fundamental objective, a metallurgical industrial sector faces some of the most difficult sustainability challenges of any industrial sector. On the other hand, the ...
A new ecologically friendly process for the synthesis of selective flotation reagents
(Association of the Chemical Engineers of Serbia, 2009)
A new ecologically friendly synthesis of N-alkyl-O-ethylthioncarbamates from ethyl dixanthogenates, waste material from the xanthate production plant, and monoalkylamines has been performed in this work. Structure determination ...
Viscosity of binary non-electrolyte liquid mixtures: Prediction and correlation
(Association of the Chemical Engineers of Serbia, 2008)
The viscosity of 31 binary liquid mixtures containing diverse groups of organic compounds, determined at atmospheric pressure: alcohols, alkanes (cyclo and aliphatic), esters, aromatics, ketones etc., were calculated using ...
A mass transfer heterogeneous in systems by the adsorption method
(Association of the Chemical Engineers of Serbia, 2009)
A mass transfer coefficient between: A liquid and single sphere and a liquid And a column wall in packed and fluidized beds of a spherical inert Particle have been studied experimentally using the adsorption method. The ...
A novel bioreactor with mechanical stimulation for skeletal tissue engineering
(Association of the Chemical Engineers of Serbia, 2009)
The provision of mechanical stimulation is believed to be necessary for the functional assembly of skeletal tissues, which are normally exposed to a variety of biomechanical signals in vivo. In this paper, we present a ...
