研究了碱性水溶液中无机化合物分解H 2 O 2 时出现单线态氧(O 2 )的可能性。使用红荧烯-2,3,8,9-四羧酸四钾作为捕集器，通过HPLC检测得到内过氧化物。我们发现四种矿物化合物会导致内过氧化物的形成：碱土金属Ca、Sr和Ba的氧化物； d构型第3A、4A、5A和6A族元素的衍生物（铌除外）；锕系元素和镧系元素的氧化物；最后是氧化剂 CIO-、BrO-、Au3+、I03" 和 I04-。选择每个家族中的一种化合物进行进一步研究，以加强* 02 假说。因此，当将母体化合物引入到以下物质的混合物中时，9,10-二苯基蒽-2,3,6,7-四甲酸四钾的内过氧化物的产率得到提高： H202+(CIO-,Nd2O3,Mo042-,Ca(OH)2)+氘化水代替轻水。
The possibility of singlet oxygen (O2) occurrence in the decomposition of H202 by mineral compounds in aqueous basic solutions was examined. Tetrapotassium rubrene-2, 3, 8, 9-tetracarboxylate was used as a trap, giving an endoperoxide detected by HPLC. We found that four families of mineralcompounds lead to the formationof the endoperoxide: the oxides of the alkaline earths Ca, Sr, and Ba; the derivatives of elements of groups 3A, 4A, 5A, and 6A in d configuration (except niobium); theoxides of actinides and lanthanides; and finally the oxidizers CIO-, BrO-, Au3+, I03", and I04-. One compound in each family was selected for further investigation in order to strengthen the* 02 hypothesis. Thus, the yield of the endoperoxide of tetrapotassium 9, 10-diphenylanthracene-2, 3, 6, 7-tetracarboxylate was enhanced when the parent compound was introduced in a mixture of H202+(CIO-, Nd203, Mo042-, Ca (OH) 2)+ deuteratedwater instead of light water.
