研究了酰胺/膦酸酯型树脂483C_1[CONHCH_2CH_2P(O)(OR)_2]从盐酸中吸金的化学问题.结果表明平衡服从Freundlich吸附等温式,AuCl_4~-以缔合机制吸着;测得了AuCl_4~-的内扩散系数为5.8×10~(-9)cm~2·s~(-1)以及HCl-硫脲为解吸剂时的有关动力学参数;还研究了AuCl_4~-的柱穿透曲线.
The chemical problem of the absorption of gold from hydrochloric acid by 483C_1 [CONHCH 2 CH 2 P (O) (OR) 2] was studied. The results showed that the equilibrium was adsorbed by Freundlich adsorption isotherm and AuCl 4 - - the internal diffusion coefficient of 5.8 × 10 -9 cm 2 s -1 as well as the kinetic parameters of HCl-thiourea as desorbent. The column breakthrough curves of AuCl 4 ~ .
