BPA direct photodegradation was very slow in pure aquatic system; but was rapid in alkalinesystem and nitrate solutions according with first grade dynamic equation.
结果表明，BPA在纯水体系中直接光解很慢，但在碱性体系和硝酸根溶液中光解迅速，符合一级动力学反应。

When PTFE washers are used in systems using water-reactive acidic or basic gases, their moisture can cause the formation of corrosive acids or alkaline liquids in the system.
The results showed that, higher resolution and reproducibility of gliadin HPCE separations were obtained by using the alkaline sodium borate buffer system and an improved capillary cleaning procedure.
