目的评价四乙基乙二胺(TAED)对过硼酸钠放氧的影响，并与过硼酸钠-过氧化氢(H_2O_2)、过氧乙二酸钠-蒸馏水混合物进行比较。方法分为6组：对照组(I~III组)，过硼酸钠与蒸馏水、3%或30%H_2O_2混合；实验组(IV~VI组)，过硼酸钠与TAED按不同比例混合后加入蒸馏水。在室温(25℃)和体温(37℃)下，在1min、1-6h和12h以及持续到1周的每一天，用数字氧气计测量样品的氧释放量。结果TAED组在25℃和37℃下1min、1h和1min的氧释放量均显著高于对照组(P<0.05)。在所有其他测量时间，每种混合物中TAED的量不会改变放氧量和放氧速度(P>；0.05)。结论四乙酰乙二胺组在25℃和37℃时分别提前2 h和1 h达到最大释氧量。因此，TAED加速了过硼酸钠-蒸馏水混合物的氧气释放，无论其比例如何，最长可达24小时。
Aim To evaluate the effect of tetra acetyl ethylene diamine (TAED) on oxygen release from sodium perborate and to compare it with sodium perborate-hydrogen peroxide (H2O2) and sodium perborate-distilled water mixtures.Methodology Six groups were evaluated: control groups (groups I-III), sodium perborate was mixed with distilled water or 3% or 30% H2O2; experimental groups (groups IV-VI), sodium perborate was mixed with TAED in different ratios and then distilled water was added to these mixtures. The amount of oxygen released from the samples was measured with a digital oxygen meter at room temperature (25 degrees C) and body temperature (37 degrees C) after 1 min, 1-6 h and 12 h and on each day up to 1 week. The results were statistically evaluated by one-way analysis of variance and post hoc Tukey's tests.Results The TAED groups demonstrated significantly higher amounts of released oxygen after 1 min and 1 h at 25 degrees C and 1 min at 37 degrees C (P < 0.05). At all other measurement times, the amount of TAED in each mixture did not alter the amount or speed of oxygen release (P > 0.05).Conclusions Tetra acetyl ethylene diamine groups achieved their maximum oxygen release 2 h earlier at 25 degrees C and 1 h earlier at 37 degrees C than the other groups. Thus, TAED accelerated oxygen release from sodium perborate-distilled water mixtures regardless of its proportions up to 24 h.
