The Determination of Inorganic Sulphate in Sodium Lauryl Sulphate
The official method for the determination of inorganic sulphate in sodium lauryl sulphate is time‐consuming. Separation of organic and inorganic sulphate via the lead salts followed by complexometry leads to a rapid and convenient method with readily reproducible results.
The use of benzidine dihydrochloride for sulfate determinations : A direct conductometric titration method
Abstract Sulfate in small quantities may be determined by direct conductometric titration with standard benzidine dihydrochloride solution within a maximum error of less than one percent. Optimum conditions have been determined for the procedure.
Organic geochemical characteristics and depositional setting of Tertiary organic-rich sediments from onshore Penyu Basin, Malaysia
Due to the poor knowledge of the organic facies characteristics of the eastern Chenor Pahang has made it remain an untapped potential in the Penyu Basin. Therefore, detailed geochemical and petrographic characterization of the Tertiary organic facies of the eastern Chenor area of the Penyu Basin was carried out to characterized its organic matter (OM) source input. Towards achieving the goal, this study focuses on determination of organic matters richness, type and origin as related to their paleoenvironmental conditions of the carbonaceous mudstone and shale using organic petrography combined with organic and inorganic geochemistry. The sedimentary succession is characterized by fine to coarse grained sandstone occurring in association with carbonaceous mudstone and shale in a predominantly fining upward sequence within a lacustrine environment. These facies are generally enriched in organic matter as indicated by the TOC results, hydrocarbon yield (S2) and extractible organic matter (EOM), suggesting significant hydrocarbon generation potential for the area.
