【摘要】：为研究不同有机酸对磷酸三钙的溶解作用,将草酸等10种有机酸施加到磷酸三钙无机磷培养基中培养6 d,测定培养基中速效磷的含量,并对溶解磷酸三钙能力较强的5种有机酸进行正交试验,进一步比较研究其解磷能力。试验结果表明,这10种有机酸都可以促进磷酸三钙的溶解,但它们的溶磷能力却有显著差异。其中草酸、酒石酸、丙酮酸、乳酸及乙酸等5种有机酸溶磷能力较强,苹果酸、α-戊二酸的溶磷能力较弱,丙酸、富马酸、柠檬酸溶解磷酸三钙的能力最弱。对5种溶磷能力较强的有机酸进行正交试验结果表明,它们溶解磷酸三钙的能力由强到弱依次是:酒石酸、丙酮酸、乳酸、草酸、乙酸。
[Abstract]:In order to study the dissolution effect of different organic acids on tricalcium phosphate, 10 kinds of organic acids, such as oxalic acid, were applied to the culture medium of tricalcium phosphate inorganic phosphorus for 6 days, and the content of available phosphorus in the medium was determined. Five organic acids with strong ability to dissolve tricalcium phosphate were studied by orthogonal experiments. The results showed that all of the 10 organic acids could promote the dissolution of tricalcium phosphate, but there were significant differences between them. Among them, oxalic acid, tartaric acid, pyruvate, lactic acid and acetic acid were the most effective organic acids, malic acid and 伪 -glutaric acid were weak, propionic acid, fumaric acid and citric acid had the weakest ability of dissolving tricalcium phosphate. The results of orthogonal experiments on five organic acids with high phosphorus solubility showed that their ability to dissolve tricalcium phosphate from strong to weak was tartaric acid, pyruvate, lactic acid, oxalic acid and acetic acid.
