Abstract

Thiosulfate gold leaching is a green gold extraction technology. Here, the effects of thiosulfate, copper ion, ethylenediamine, and polarization voltage on the dissolution of gold in this system were investigated by an electrochemical method. The results showed that the addition of thiosulfate promoted the dissolution of gold, but increasing the thiosulfate concentration had a little additional effect. The addition of ethylenediamine also increased the dissolution of gold, but the dissolution resistance of gold increased after adding ethylenediamine. The dissolution of gold increased, the diffusion resistance increased, and the dispersion effect increased upon increasing the copper ion concentration. The copper–ethylenediamine–thiosulfate system did not display passivation (or only weak passivation) upon increasing the polarization voltage, which indicates that the system was relatively stable. The influence of three factors on the dissolution of gold followed the order thiosulfate > copper ion > ethylenediamine.

Abstract

This study was conducted to investigate the effects of 60Co γ-radiation and electron-beam irradiation on the color of dried chili products through comparative analysis of the color difference, non-enzymatic browning index, color value, and R/Y value. The experiment included different doses (0, 3, 7, and 16 kGy) and different storage times (0 and 30 d). The results revealed that when no storage time elapsed (0 d), the a* value decreased by 13% in the dried chili samples treated with a 60Co γ-ray dose of 16 kGy; the non-enzymatic browning value increased by 12%, and the R/Y value decreased by 16%. Moreover, the a*, b*, and L* values of the samples treated with electron beams at 7 kGy were significantly lower than those treated with 60Co γ-rays. Furthermore, increasing the dosage of either the 60Co γ-rays or electron beam resulted in large color differences and small non-enzymatic browning values for the chili powder samples stored for 0 d. Notably, at a dose of 16 kGy, ΔE* of the chili powder treated with 60Co γ-rays was higher than that of the powder subjected to electron-beam treatment. By contrast, the non-enzymatic browning value of the 60Co γ-ray-treated sample was significantly lower than that of the electron-beam-treated sample. After 30 d of storage, ΔE* of the chili powder samples treated with a 7 kGy dose of either 60Co γ-rays or electron beam was significantly higher than that recorded for the other dosage groups. Further, ΔE* was the highest for the samples treated with a 7 kGy dose of 60Co γ-rays. In conclusion, the impact of electron beams on the color of the dried chili products was less than that of the 60Co γ-rays. Furthermore, the effect of irradiation on the color of the chili powder was stronger than that on the color of the dried chilis.

Abstract

Machine reading comprehension have been intensively studied in recent years, and neural network-based models have shown dominant performances. In this paper, we present a Sogou Machine Reading Comprehension (SMRC) toolkit that can be used to provide the fast and efficient development of modern machine comprehension models, including both published models and original prototypes. To achieve this goal, the toolkit provides dataset readers, a flexible preprocessing pipeline, necessary neural network components, and built-in models, which make the whole process of data preparation, model construction, and training easier.
