LC/DAD determination of biogenic amines in serum of patients with diabetes mellitus, chronic urticaria or Hashimoto's thyroiditis
(Srpsko hemijsko društvo, Beograd, 2016)
Biogenic amines are integral part of nearly every cell. In the present study, the method of acidic extraction of histamine (His), of polyamines putrescine (Put), spermidine (Spd) and catecholamines epinephrine (Epi) and ...
Investigation of different extraction procedures for the determination of major and trace elements in coal by ICP-AES and ion chromatography
(Srpsko hemijsko društvo, Beograd, 2016)
This paper presents the extraction of major and trace elements from a coal sample, in deionized water, by using three different extraction techniques. Rotary mixing and ultrasonic extraction were examined for different ...
Aqueous extraction of anions from coal and fly ash followed by ion-chromatographic determination
(Srpsko hemijsko društvo, Beograd, 2016)
Three different techniques were applied for the aqueous extraction of anions from coal and fly ash: rotary mixer-and ultrasonic-assisted extraction with different duration time, and microwave-assisted extraction at different ...
Comparison of sequential and single extraction in order to estimate the environmental impact of metals from fly ash
(Srpsko hemijsko društvo, Beograd, 2016)
The aim of this paper is to simulate leaching of metals from fly ash in different environmental conditions using ultrasound and microwave-assisted extraction techniques. Single-agent extraction and sequential extraction ...
Ultrasound and shacking-assisted water-leaching of anions and cations from fly ash
(Srpsko hemijsko društvo, Beograd, 2016)
Two mechanical extraction techniques were used for the extraction of environmentaly interesting components of coal fly ash: shaking, during which the extraction process lasted from 6 up to 24 h, and sonication that lasted ...
Influence of bunch morphology on quality of wines produced from clones of grape variety Prokupac
(Srpsko hemijsko društvo, Beograd, 2016)
Wine quality depends mainly on the characteristics of the grape it is made of, and one of the attributes affecting wine composition is cluster and berry morphology. The aim of this study was to represent variability of the ...
