本文通过测定Am、D.、在降解的有机溶液和选定的HNO 3浓度的水溶液之间的关系，并通过使用气相色谱分析测量降解溶液中的O-β-D（IB）CMPO的浓度。通过在50°C下连续搅拌十氢萘和0 μ D（1B）CMP 0的CCH溶液与5 M HNO 3来进行水解。以类似的方式进行辐解，同时用来自60 Co源的γ射线照射双相系统。从实验数据中得到的证据表明，0-D（iB）CMPO的降解方案，其中涉及甲基（辛基）-（苯基）-氧化膦（MO-PO）和辛基（苯基）次膦酸（H[0-P]）的形成。提出的降解方案已通过测量从MO·PO和O·D（iB）CMPO以及H[CHOP]和O·D（iB）CMPO的混合物中的DAm进行了实验验证。有证据表明，莫杰波可以...
ABSTRACT The hydrolytic and radlolytic degradaton of octyl(phenyl)-N,N-dIIsobutylcarbamoylmethylphosphine oxide [0ϕD(lB)CMPO] has been investigated by measuring the distribution ratio of Am, D., between degraded organic solutions and aqueous solutions of selected HN03 concentrations and by measuring the concentration of OϕD(IB)CMPO In degraded solution using gas chromatographic analysis. Hydrolysis was performed by continuous stirring of decalin and CCH solutions of 0ϕD(lB)CMP0 with 5 M HNO3 at 50°C. Radiolysis was performed in a similar manner while irradiating the biphasic system with gamma rays from a 60Co source. From the experimental data, evidence was obtained for a degradation scheme of 0ϕD(iB)CMPO which Involves the formation of methyl(octyl)-(phenyl)-phosphine oxide (MOϕPO) and octyl(phenyl)phosphinic acid (H[0ϕP]). The proposed degradation scheme has been experimentally verified by measuring DAm from mixtures of MOϕPO and OϕD(iB)CMPO and of H[ϕP] and OϕD(iB)CMPO. Evidence was found that MOϕPO ca...
