An empirical equation has been developed that predicts nitric-acid extraction from aqueous nitric-acid/sodium-nitrate solutions by tri-n-butyl phosphate (TBP) solutions. The predicted nitric-acid concentrations in the organic phase, for both 20 and 30 vol% TBP, are generally within 卤0.02 M ...

bisulfate. One involves mixing sodium hydroxide with sulfuric acid which will react to form sodium bisulfate and water as shown in the equation below. This method, produced by JOST Chemical® (Jost Chemical 2014), results in a sodium bisulfate monohydrate which is used as a laboratory reagent....
The petitioner states that they use another sodium bisulfate production method that involves reacting sodium chloride (salt) and sulfuric acid at elevated temperatures to produce sodium bisulfate and hydrogen chloride gas as shown in the equation below. NaCl + H2SO4 → NaHSO4 + HCl According to ...

Equation (1) was used to compare the difference between individual weight and average weight to determine weight variation. Weight variation(%)=(Individual weight−Average weightAverage weight)×100Weight variation%=Individual weight−Average weightAverage weight×100 (1) 2.4.2. Thickness and ...
Porphyra tenera (PT) is a functional seaweed food that has been reported for health benefits such as antioxidant, immunostimulant, anti-inflammation, and hepatoprotective effects. In this study, we investigated the effect of PT extracts on gut microbiota
The elemental composition of the concentrate was determined using atomic absorption spectrometry (AAS) on an AA-6200 spectrometer (Shimadzu, Japan); preliminary decomposition of the sample with concentrated nitric acid at 90–95 °C and a pressure of 10 atm was performed prior the copper content ...
