This study analysed the spatial and temporal occurrence of 29 disinfection by-products (DBPs) formed by chlorination and chloramination. Four full-scale treatment works, and distribution system locations were sampled, and the results were compared with laboratory-based simulated distribution system (SDS) tests. The DBPs monitored incorporated 4 tri...

Defluorination roasting of lepidolite ore in a fluidized bed reactor has been proposed for improving the extraction efficiency of lithium. In this paper, a vacuum was introduced to the fluidized bed reactor, which significantly improved the defluorination efficiency of lepidolite particles. This improvement could be attributed to an increase in the...

Present-day all-vanadium redox flow batteries (VRFBs) generally require high purity vanadium oxide as a raw ingredient. The chlorination procedure presents distinct technical advantages with regard to preparing high purity vanadium pentoxide (V2O5) using vanadium oxytrichloride (VOCl3) as a highly pure intermediate. To efficiently prepare high puri...

In this work, a two-step zircon method to produce zirconium oxychloride was introduced, and the alkali fusion technique with NaOH and water leaching process were investigated. The effects of the operating conditions on the decomposition of zircon were determined, and the optimal conditions are as follows: alkali/zircon mass ratio of 0.7 at the firs...
An efficient and catalyst-free method for the preparation of optically active and racemic mono-substituted t-butyl phosphinic chlorides (BuRP)-Bu-t(O)Cl under flow conditions was reported. A variety of mono t-butyl substituted phosphinic chlorides were obtained using this protocol starting from the corresponding phosphine oxide and one equivalent o...
The separation of gold and vanadium in the refractory carbonaceous gold ore had been performed by one-step roasting method. The thermodynamic viability of the possible reactions in the process was analyzed based on thermodynamic data. And the effects of experimental parameters such as roasting temperature, roasting time and NaCl dosage on the recov...
