Caffeine removal efficiency was less in acidic solutions (initial pH 4), and insignificant degradation was observed in alkaline solutions (initial pH 10). Furthermore, the degradation of caffeine was also enhanced by increasing the input power in DBD system. The DBD system used in this study ...
respectively (Table1). Water pH was in the alkaline range at R and A sites while it was slightly acidic in S and J sites (Fig.2). The mean EC of the analysed water samples at the four sites fluctuated between 40 and 46 μS cm−1. The TDS concentration...
Sodium bicarbonate will react with acids, acidic salts, and many alkaloidal salts, and it will evolve carbon dioxide. It can also intensify the darkening of salicylates. Sodium bicarbonate should be preserved in well-closed containers.5 Silica g...
The method comprises: a pre-treating step of selecting and gathering squid skin, washing the squid skin with alkaline electrolytic water, and sterilizing and disinfecting the squid skin with acidic electrolytic water; a drying step of drying the pre-treated squid skin to have a moisture content ...
