Adsorbents with hydrophilic and hydrophobic natures were designed by intercalating a bioderived molecule; 4,4′-diammonium-α-truxillic acid (4ATA) and 4,4′-diammonium-α-truxillic acid dimethyl ester (E4ATA), which both are bioderived molecules, into a smectite (purified bentonite) to concentrate o-phenylphenol and biphenyl, respectively, from water. The adsorption isotherm showed high affinity between the 4ATA-smectite hybrid and o-phenylphenol with a high Langmuir constant (0.98 L mg^–1). Meanwhile, the E4ATA-smectite hybrid adsorbed biphenyl with a high Langmuir constant (3.61 L mg^–1). The adsorption properties of 4ATA- and E4ATA-smectite hybrid were contributed by the chemical characteristics of 4ATA and E4ATA in the interlayer space of the smectite.

蒙皂石与 4,4'-二铵-α-特鲁西酸及其甲酯的纳米结构用于去除水中的邻苯基苯酚和联苯

通过插入生物源分子设计具有亲水性和疏水性的吸附剂；将生物衍生分子 4,4'-二铵-α-特鲁西酸 (4ATA) 和 4,4'-二铵-α-特鲁西酸二甲酯 (E4ATA) 转化为蒙皂石（纯化膨润土）以浓缩邻苯基苯酚和联苯，分别来自水。吸附等温线显示 4ATA-蒙皂石杂化物与邻苯基苯酚之间具有高亲和力，具有高 Langmuir 常数 (0.98 L mg ^–1 )。同时，E4ATA-蒙皂石杂化物以高朗缪尔常数（3.61 L mg ^–1 ）吸附联苯。 4ATA-和E4ATA-蒙脱石杂化物的吸附性能是由蒙脱石层间空间中4ATA和E4ATA的化学特性决定的。
