Abstract：The adsorption of isoproturon and two model
compounds, N,N-dimethylurea and4-isopropylaniline, on clay minerals (bentonite,montmorillonite and kaolinite), organic matter (humic acid) and soil (with and without organic matter) has been studied using FT-infrared spectroscopy (IR), thermogravimetric analysis (TGA), high pressure liquid chromatography (HPLC) and X-ray diffraction (XRD).N,N-dimethylurea interacted with bentonite and montmorillonite by the coordination of the carbonyl group, directly or indirectly through water molecules, with exchangeable cations. Adsorption on humic acid was due to hydrogen bonding with the active sites of the adsorbent. The amino group ofN,N-dimethylurea appears tobe relatively inactive during adsorption. The mechanisms involved in the adsorption of 4-isopropylaniline were hydrogen bonding and protonation. No adsorption of 4-isopropylaniline was
observed on kaolinite. The investigation of isoproturon suggested that both the carbonyl and amino groups of isoproturon were involved in interactions with the active sites of the adsorbents. Both the clay minerals and organic matter of soil contribute to the adsorption of organic compounds on soil but the clay minerals bentonite and montmorillonite play a major role in their adsorption on soil.

Abstract：H-magadiite was applied to remove the pesticides
2,4-D, diuron, and atrazine from water. The H-magadiite containing herbicides adsorbed were investigated by FTIR, DRX, N2 adsorption and desorption isotherms, and surface area. Calorimetric studies were carried out to determine the heat of
interaction between pesticides and magadiite. It was possible to ride the cycle of interaction of magadiite–pesticide for a better understanding of the process involved. From the results of
the
thermal
effect
of
the
interaction
of
magadiite–pesticide, the thermochemical parameters can be determined by using the relationship between the data obtained from adsorption and calorimetry results. The interaction of pesticide–magadiite follows the sequence of adsorption: diuron > atrazine > 2,4-D. The ΔH values for the interactions were determined to be ?20.62 ± 1.08, ?24.04 ± 0.86–26.34 ± 0.93 kJ mol?1 for 2,4-D, diuron and atrazine, respectively. All the interactions were spontaneous, enthalpically and entropically favored demonstrating the effectiveness and efficiency of the method.

Abstract：Surfactant-bentonite complexes (organo-clays)
with
different
amounts
of
adsorbed
dodecyltrimethylammonium bromide (DTAB) were prepared. The adsorption of the pesticides paraquat and biphenyl from aqueous solution on clays was studied by the batch method with radiotracers. — On organo-clays the preferentially adsorbed di-cation paraquat only partially replaces the mono-cationic surfactant. This result was supported by investigations
with
microcalorimetry
and
x-ray
diffraction. — On the contrary, the adsorption of the hydrophobic biphenyl is enhanced with an increased amount of adsorbed DTAB by hydrophobization of the bentonite.
6、Bentonites: adsorbents of toxic substances（膨润土：
对有毒物质的吸附作用） Author: G. Lagaly

Abstract：The use of bentonites as adsorbents results from
the reactivity of montmorillonite which is the main mineral in this clay-like material. Montmorillonite, a 2:1 clay mineral, impresses by a diversity of reactions in the interlayer space and at the external surfaces, which are the cause of strong adsorption of heavy metal ions and organic compounds. Bentonite adsorbents are used as crude bentonite, in soda-activated form, after degradation to bleaching earths, after modification by organic cations, or in form of polyhydroxometal or polyoxometal derivatives (“pillared clays”). The ease with which the bentonites are modified allows an optimization of the properties so that the requirements of numerous practical applications are fulfilled.
