【摘要】：為研究不同有機(jī)酸對(duì)磷酸三鈣的溶解作用,將草酸等10種有機(jī)酸施加到磷酸三鈣無(wú)機(jī)磷培養(yǎng)基中培養(yǎng)6 d,測(cè)定培養(yǎng)基中速效磷的含量,并對(duì)溶解磷酸三鈣能力較強(qiáng)的5種有機(jī)酸進(jìn)行正交試驗(yàn),進(jìn)一步比較研究其解磷能力。試驗(yàn)結(jié)果表明,這10種有機(jī)酸都可以促進(jìn)磷酸三鈣的溶解,但它們的溶磷能力卻有顯著差異。其中草酸、酒石酸、丙酮酸、乳酸及乙酸等5種有機(jī)酸溶磷能力較強(qiáng),蘋(píng)果酸、α-戊二酸的溶磷能力較弱,丙酸、富馬酸、檸檬酸溶解磷酸三鈣的能力最弱。對(duì)5種溶磷能力較強(qiáng)的有機(jī)酸進(jìn)行正交試驗(yàn)結(jié)果表明,它們?nèi)芙饬姿崛}的能力由強(qiáng)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 偽 -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.
