本文利用过氧乙酸联合过氧化氢、柠檬酸对马尾松TMP浆进行处理,紫外分光光度法测定其甘油三酸酯含量,结果表明,经过氧化剂化学法处理后,甘油三酸酯的降解率最高可以达到24%,并且发现柠檬酸具有一定的辅助渗透作用。
The change of tiglyceride content was measured with ultraviolet spectrophotometric method.
利用脂肪酶结合表面活性剂对树脂模拟物进行处理,选出合适的表面活性剂并确定其用量,进而对马尾松TMP浆进行处理,紫外分光光度法测定其甘油三酸酯含量变化,结果表明,经过进一步表面活性剂处理后,甘油三酸酯的降解率由脂肪酶处理后的8%提高到26%。
