Phosphine residues were determined in 2 types of rice samples, raw polished and parboiled. The yellow chromophore due to phosphine from raw polished rice had 2 absorption maxima, a strong one at 370-380 nm and a weaker one at 400-410 nm. The chromophore from parboiled rice also had 2, one at 390-400 nm and the other at 410-420 nm. A closed system containing rice and a phosphine tablet or powder yielded 93-99% recovery of fortified phosphine. At any given dose of phosphine, parboiled rice retained a higher amount of residue after aeration than did raw polished rice.
对两种大米样品（精白米和蒸谷米）中的磷化氢残留量进行了测定。精白米中磷化氢产生的黄色发色团有两个吸收最大值，一个在370 - 380纳米处较强，另一个在400 - 410纳米处较弱。蒸谷米中的发色团也有两个，一个在390 - 400纳米处，另一个在410 - 420纳米处。含有大米和磷化氢片剂或粉剂的封闭系统对强化磷化氢的回收率为93 - 99%。在任何给定的磷化氢剂量下，通气后蒸谷米残留的磷化氢量高于精白米。
