The calcium-xylenol orange-cetyltrimethylammonium bromide-ethanol system was studied and used for the determination of trace calcium in sputum from patients with chronic pneumonia. The results showed that the calcium content in serum was higher than that in human serum High calcium content, but also higher than the human extracellular fluid calcium content.
