In the ascorbic acid method, phosphomolybdic acid is formed as a result of acid digestion between ammonium molybdate and orthophosphates, and it is reduced by ascorbic acid, which gives a blue-colored compound that can be analyzed at 820 nm. The presence of cholesterol can be determined by the formation of a colored complex in the reaction between cholesterol and a freshly prepared acetic anhydride–concentric sulfuric acid mixture (20:1) at 680 nm.

The phosphomolybdic acid was synthesized by dissolving 36 g of sodium molybdate dihydrate in 90 mL of deionized water (kept at 80 °C in an oil bath) under vigorous stirring (Llewelyn 2010; Yehia et al. 2017). When all the Na2MoO4.2H2O had completely dissolved, 8 g of disodium hydrogen phosphate was added and stirred for another 30 min. 40 mL of HCl was added dropwise at 60 °C to change the produced heteropoly anion into heteropoly acid. The acidification of the solution should reach a pH value of 1.5–2 (Chamack et al. 2014). Heteropoly acids have high solubility in diethyl ether, so it is applicable for HPMo extraction from an acidic solution (Llewelyn 2010). The HPMo extracted from the bottom of the separatory funnel was dried at 60 °C and calcined in air at 250 °C.

The applied spectrophotometric method involved the formation of phosphomolybdic acid by a reaction in an acidic aqueous solution of ammonium molybdate, potassium antimony tartrate and orthophosphates, followed by its reduction to molybdenum blue by ascorbic acid [39].
