Sewer wastewater systems pose great threats to OPC-based concretes used for pipes due the presence of various acids. Phosphoric acid can cause as much damage sulphuric but has been very lightly studied. This study focuses on early stage degradation process different cementitious materials in phosphoric acid. Three types are compared: OPC (100% cement), slag-blended (slag/cement mass ratio at 65...
Low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. It was thought that the HPLC is the best method of the determination of organic acids in the apple juice. In this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for ...
Lipids comprise the primary component of cell membranes. Imaging mass spectrometry is increasingly being used to visualize membranous lipids in clinical specimens, and it has revealed that abnormal lipid metabolism is related to the development of diseases. To characterize cell populations which are rare and sparsely localized in tissues, we conducted time-of-flight secondary ion mass spectrome...
Oil palm empty fruit bunch (OPEFB) was pretreated using white-rot fungus Pleurotus floridanus, phosphoric acid or their combination, and the results were evaluated based on the biomass components, and its structural and morphological changes. The carbohydrate losses after fungal, phosphoric acid, and fungal followed by phosphoric acid pretreatments were 7.89%, 35.65%, and 33.77%, respectively. ...
The phosphoric acid compounds of the blood may be divided into three groups: protein, lipoid, and acid-soluble (1, 2, 3, 4). In the last are included those compounds that are not precipitated with the proteins and lipoids when the blood is treated with the usual acid protein precipitants. In plasma, this acid-soluble phosphorus seems to consist almost entirely of inorganic phosphate (3, 4, 5, 6...
The economics of the inedible oilseed crop Brassica carinata as a source renewable fuels can be enhanced by converting its cellulosic biomass to value-added chemicals, such organic acids. We investigated biochemical conversion propionic acid first pretreating meal (CM), which is obtained after extraction oil from seeds, with concentrated phosphoric remove hemicellulose and gain access cellulose...
