Determination of sulfur in crude oils and related materials with a Parr bomb digestion method and inductively coupled plasma atomic emission spectrometry

Development and Evaluation of a Novel Sulphur Analysis Method

“…Either solid or liquid samples can be combusted with a relative high sample mass (0.5 g to 1.5 g) in comparison to other combustion methods [8]. The method has been used for the simultaneous determination of elements (Br, F, Cl, and S) in different types of samples (coal, oil, shredder residues, and diesel) and obtained a high efficiency [4], [9], [10]. Generally contamination is considered to be low, but are present in cases where the bomb is not cleaned effectively between different types of samples and if the absorbing solution contains trace elements.…”

“…For sample dissolution the oxygen bomb, also known as Parr bomb, is a highly preferred method of combustion due to its ability to completely combust organic samples providing a clean solution [4]. Either solid or liquid samples can be combusted with a relative high sample mass (0.5 g to 1.5 g) in comparison to other combustion methods [8].…”

“…The method is considered to be semiquantitative due to interferences persisting when highly concentrated acids are used during the sample preparation step [7]. Although ICP-OES is not as precise as energy dispersive X-ray fluorescence (EDXRF) due to interference effecting the emission intensity and accuracy, it is a cheaper and faster analytical technique [4].…”

“…The prescribed analytical techniques for these dissolution methods are recommended based on sample types (organics, heavy-crude oils, coal, and waste material) with respect to matrix interferences, trace elements and concentrations [4], [6], [7].For the successful development of a new analytical method, the different components of the dissolution and analyses needs to be investigated.…”

“…Thus, various industries rely on both quantitative and [2]. It is therefore important to develop an innovative, fast, accurate, and precise method to determine elemental sulphur concentrations with an eco-friendly and cost-effective analytical technique [3], [4].…”
