Abstract

The results of adsorption of synthesized lithium folate Li₂C₁₉H₁₇N₇O₆ · 5H₂O, bovine serum albumin, acid–base indicators, and some dyes from aqueous solutions on ultradispersed nanodiamond of UDA-SP grade are presented. Data on the adsorption of cationic and anionic dyes, measurement of the suspension effect and ζ potential may indicate that the nanodiamond has a negatively charged surface in the working pH range of adsorption (6.0–7.5). The isotherms of folate ion, lithium ion, and bovine serum albumin appeared to be of Langmuir type, and the saturation sorption values were 1.05, 1.14 mmol/g, and 180 mg/g, respectively. Equilibrium constants of the sorption–desorption processes for lithium folate ions have also been determined.

水溶液中某些物质在超分散纳米金刚石上的吸附

摘要

合成叶酸锂Li ₂ C ₁₉ H ₁₇ N ₇ O ₆ ·5H ₂的吸附结果O，牛血清白蛋白，酸碱指示剂和UDA-SP级超分散纳米金刚石上水溶液中的一些染料被介绍。关于阳离子和阴离子染料的吸附数据，悬浮效果和ζ电位的测量结果可能表明，纳米金刚石在吸附的工作pH范围内（6.0-7.5）具有带负电的表面。叶酸离子，锂离子和牛血清白蛋白的等温线似乎是Langmuir型，饱和吸附值分别为1.05、1.14 mmol / g和180 mg / g。还确定了叶酸锂离子吸附-解吸过程的平衡常数。
