Optimization of process cod bone soluble calcium extraction

With cod bone as raw material and using the atomic absorption spectrophotometry assay cod bone soluble calcium content.The acid extraction method was used for extracting cod bone calcium.Application of response surface analysis was applied to optimize the concentration of hydrochloric acid,extractive temperature,reacting time and material liquid ratio.The results showed that cod bone soluble calcium extractive technology conditions was the concentration of hydrochloric acid 3 mol/L,extractive temperature of 108 ℃,reacting time for 60 min,material liquid ratio of 1∶4(m∶V).On this condition cod bone soluble calcium extractive efficiency can reach 22.36%.
