Sulfonamides are frequently detected in surface water and groundwater, which have the characteristics of low concentration, high toxicity, and being difficult to remove. In this study, an electro/peroxydisulfate system catalyzed with activated carbon (EC/AC/PS) was used to treat sulfamethoxazole (SMX). The results showed that the removal efficiency of SMX was 88.5% by the EC/AC/PS system. An increase...
Diffusive gradients in thin films (DGT) technology has been increasingly proved to be a promising tool for accurately predicting plant-available phosphorus (P) in soil using air-dried samples. However, the effects of the air-drying process on DGT-measured P are unknown compared to those of using moist samples in which plant roots survive throughout a growing season. We investigated the differences...
To quantitatively characterize the evolution process of disaster-causing stress fields and to analyze the whole time domain characteristics of a stope from moving to stability, we constructed the four-dimensional time-space structure model of deep stope using PFC discrete element modeling software, and embedded transducers in the goaf area to monitor overlying strata movement characteristics. Targeting...
