Iron oxide activation of persulphate as measured by orange G degradation

This data set is a record of laboratory experiments performed to evaluate the effectiveness of persulphate activation by the three common iron oxides, magnetite, maghemite and haematite as measured by the degradation of a target environmental pollutant, orange G. Data presented in Excel spreadsheets showing the effect of the presence of persulphate, magnetite oxidation, iron oxide mineralogy, concentration of hydroxyl groups on haematite, size of particle, coating by co-existing silica and carbonate minerals. Also presented are data for dissolved iron as ferrous and ferric ion activation of persulphate, the degree of dissolution of iron oxides during persulphate activation and the influence of pH and phosphate buffering on iron oxide activation of persulphate. The characterisation of the iron oxide particles using N2 adsorption, colorimetry, magnetometry, xray diffraction and infrared spectroscopy are also presented.本数据集为实验室实验记录，旨在通过目标环境污染物橙G（Orange G）的降解效果，评估三种常见铁氧化物——磁铁矿（magnetite）、磁赤铁矿（maghemite）与赤铁矿（haematite）对过硫酸盐（persulphate）的活化效能。本次公开的Excel电子表格（Excel spreadsheets）数据涵盖以下因素对过硫酸盐活化效果的影响：过硫酸盐浓度、磁铁矿氧化状态、铁氧化物矿物学特征、赤铁矿表面羟基浓度、颗粒粒径、共存硅质与碳酸盐矿物的包覆作用。此外，数据集还包含溶解态亚铁离子与铁离子活化过硫酸盐的相关数据、过硫酸盐活化过程中铁氧化物的溶出程度，以及pH与磷酸盐缓冲体系对铁氧化物活化过硫酸盐效能的影响。本数据集同时收录了采用氮气吸附法（N2 adsorption）、比色法（colorimetry）、磁测量法（magnetometry）、X射线衍射法（X-ray diffraction）与红外光谱法（infrared spectroscopy）对铁氧化物颗粒进行的表征数据。
