氧化法与物理吸附法相结合，以骨胶为原料，过硫酸钠和酸化凹凸棒土为脱色剂，得到浅色的骨胶胶黏剂。研究了m（水）∶m（干骨胶）为1.3∶1时，过硫酸钠质量、酸化凹凸棒土质量、反应温度和反应时间对骨胶色泽的影响，并在单因素实验的基础上，通过正交试验得出骨胶脱色的最佳工艺条件为：过硫酸钠质量分数为9.3%，酸化凹凸棒土质量分数为8.0%，反应温度为50℃，反应时间为60 min，经最佳工艺制备的骨胶胶黏剂脱色率为71.13%，稳定性良好，同时骨胶的性能未发生改变。

Using bone glue as raw material,sodium persulfate and acidified attapulgite as decolorizers,light color bone glue adhesives are obtained by the combination of oxidation method and physical adsorption method.When the ratio of m(water) to m(dry bone glue) is 1.3:1,the effects of sodium persulfate content,acidified attapulgite content,reaction temperature and reaction time on the color of bone glue are studied.On the basis of single factor experiment,the optimum technological conditions are got via orthogonal test as follows:the mass fraction of sodium persulfate is 9.3%,the mass fraction of acidified attapulgite soil is 8.0%,the reaction temperature is 50℃,and the reaction time is 60 min.The bone glue adhesives prepared under the optimal conditions have a decolorization rate of 71.13% and exhibits good stability,while the performance of bone glue remains unchanged.
