The affinity of hydroxyapatite for furfural and a brown pigment formed by furfural and glycine was studied. A series of mixtures containing 1 M furfural and 0.25-2.0 M glycine were incubated at 37 degrees C and aliquots of hydroxyapatite added. The apatite showed a strong affinity for the brown pigment formed, and an excess of glycine in the mixtures appeared to enhance the binding. The adsorption of furfural to hydroxyapatite was estimated by a spectrophotometric method. The data revealed that pretreatment with CaCl2 and glycine significantly increased the adsorption of furfural.
研究了羟基磷灰石对糠醛以及糠醛与甘氨酸形成的棕色色素的亲和力。将一系列含有1 M糠醛和0.25 - 2.0 M甘氨酸的混合物在37℃下孵育，并加入等分试样的羟基磷灰石。磷灰石对形成的棕色色素表现出很强的亲和力，混合物中过量的甘氨酸似乎增强了这种结合。通过分光光度法估计糠醛对羟基磷灰石的吸附。数据显示，用氯化钙和甘氨酸预处理显著增加了糠醛的吸附。
