摘要
本文以磷酸为溶剂，采用一种新的装置溶解矿物岩石样品，气相色谱法测定二氧化碳。测定的碳酸盐标样和硅酸盐标样中的二氧化碳的相对误差分别为０．２％和－４７％；相对标准偏差分别为１．０％和３．３％。该法简单、快速，不仅适于测定矿物岩石中低含量二氧化碳，也可以测定高含量二氧化碳。
A new apparatus can be used to dissolute mineralized rock samples in thephosphtic solution as well as gas chromatography can be used to determine carbon dioxidein mineralized rocks which are described in this paperThe relative standard deviations were 1.0% and 3.7% respectively,the relative errorwere 0.2% and -4.7% respectively for carbon dioxide in carbonate standard samples andsilicate standard samoples. The method is simple and rapid. It is not only suitable to determinating the low content of carbon dioxide, but also to determinating the high content ofcarbon dioxide in mineralized rocks.
