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 ...
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 ...
A comparison of sample extraction procedures for the determination of inorganic anions in soil by ion chromatography / Uticaj pripreme uzorka zemljišta na određivanje neorganskih anjona metodom jonske hromatografije
(Srpsko hemijsko društvo, Beograd, 2011)
Three different extraction techniques were used for aqueous extraction of anions from soil of the type Ranker that was sampled from a serpentine site. The first technique involved the use of a rotary mixer (rotary mixer ...
