Mixed gel electrolytes were fabricated chemically at a temperature range of 2–5°C using some additives comparing with traditional electrolytes (1.26 g/cm 3 H 2 SO 4 ). The polyacrylamide (PAM) content is kept constant (0.2 wt%), while the propylene glycol (PPG) and o fumed silica (NFS) contents varied.

The gel electrolyte is composed of a 1:1 mixture of PVtrifluoromethanesulfonate Zn(Tf) 2 salt dissolved in BMIMTf ionic liquid and was determined to have optimal mechanical integrity and transport properties. At this composition, the room temperature gel ionic conductivity was 0.37 mScm −1.

Nov 05, 2019 · Wastewaters often contain significant concentrations of inorganic nutrients such as nitrogen and phosphate. Wastewater treatment processes removes only around 50% of N and 60% of the P. As such, the concentrations of these major nutrients are still high in processed sewage in comparison with irrigation water from other source.

However, simultaneous high-temperature/high-PH conditions should be avoided, as polymer hydrolysis can release traces of ammonia gas. Partially Hydraulised PolyAcrylamide-PHPA is added as a treatment for the cuttings and the sides of the well bore, and should be added on a regular basis while drilling shale sections.

The Cu ions leached during wastewater treatment was recycled by alkaline H 2 O 2 reaction.
