摘　　要： 研究了新生磷酸钙固相吸附剂在模拟工业糖液中对焦糖和葡萄糖碱性降解物的吸附脱色规律。发现，该固相吸附剂对这类色素的吸附特性属于Ｌａｎｇｍｕｉｒ型，但其吸附量的大小与第三组分（蔗糖）的存在有一定的关系。论文对第三组分的影响作用进行了机理探讨。 The adsorption decolourization of caramel and alkaline degradation products of glucose on fresh calcium phosphate precipitate (FCPP) adsorbent was experimentally inves tigated in the simulated industrial sugar solution. It was found that the adsorption property for the solid adsorbent belongs to Langmuir type and the adsorption magnitude of colourant on FCPP adsorbent is, to a certain degree, relative with the existence of third component (sucrose). The mechanism on the influence of third component was analyzed in the paper and mathematical models were established with the help of computer.
