Webyou want to record your units as “P” that the spectrophotometer is set up to display as PO. 4-P. If it is showing as PO. 4 3-then it is necessary to convert back to PO. 4-P by dividing your results by 3.06 as described earlier in the orthophosphate section. Acid Hydrolyzable Phosphate/Condensed . Phosphate. Structure WebPhosphate buffer (PB) pH 6.0 preparation method. By mixing solutions of Na 2 HPO 4 ·2H 2 O (6.2 ml, 0.2 M) and NaH 2 PO 4 ·2H 2 O (43.8 ml, 0.2 M) in deionized water, a stock solution of 0.1 M PB (pH 6.0) was created. The pH of the PB was adjusted at 6.0 using either concentrated HCl or KOH. 2.2. GSH sensing using UV–vis spectrophotometer
