通过在硼酸钠和碳酸钠的熔融混合物中加热金属钯,在1000 °C下加热2 h,提高了钯在水中的溶解度。以17Na2O − 83b2o3为硼酸钠,水溶液中钯的提取率为21%。硼酸钠的增溶效率因其化学成分的不同而不同。在热处理过程中,钯表面发生氧化,氧化后的钯溶解在介质中。
Solubility of palladium in water was enhanced by heating metallic palladium in a molten mixture of sodium borates and sodium carbonate at 1000 °C for 2 h. When 17Na2O − 83B2O3was used as the sodium borate, 21% of palladium in the obtained product was extracted in water. The solubilization efficiencies differed depending on the chemical composition of the sodium borate. During the heat treatment, oxidation occurred on the palladium surface and the oxidized palladium dissolved in the media.
