本文报导三种酚醛冠醚聚合物对水溶液中某些金属离子的吸附性能。这类中性络合树脂最高动态吸附容量可达0.14mmol/g,并对Ag~+—Ni~(2+)、Ag~+—Cu~(2+)、K~+—Ni~(2+)等有较好的选择性。
This paper reports the adsorption properties of three kinds of phenolic crown-crown ethers on some metal ions in aqueous solution. The highest dynamic adsorption capacity of this kind of neutral complex resin is up to 0.14 mmol / g, and the adsorption capacities of Ag ~ + -Ni ~ (2+), Ag ~ + -Cu ~ (2 +), K ~ + -Ni ~ +), Etc. have better selectivity.
