摘 要: | 采用离子色谱法测定残炭提取液中离子及其含量,并用红外光谱仪和x-荧光光谱法(EDX)分析了残炭在浸泡前后的结构变化。结果表明,在超纯水中浸泡得到磷酸根离子;在80℃温度下,震荡提取72小时后,提取液中磷酸根离子浓度达到最大值;提取后残炭中磷含量显下降,P-O-P和P-O-C结构的吸收峰显著减小。说明,残炭中大部分的P-O-P和P-O-c键水解成磷酸根,残留的P可能进入残炭的环状结构或与环状结构直接相连。

Abstract: | The kind and content of anion in the char was determinated by ion chromatography, and the structure was characterized by Fourier Transform infrared spectroscopy (FTIR) and X-ray Fluorescence Spectrometer (EDX). The re- suits showed that phosPhate group was detected in the solution; when the temperature was 80 ℃ and the soak time was 72 hours, the value of phosphate group in the solution reach the maximum; the P content decreased with the decrease of P-O-P and P-O-C absorption strength, which revealed that P-O-P and P-O-C bond were hydrolysed to phosphate group, and the residual P entered polyaromatic ring or connected to polyaromatic ring directlt. |
