The sorption of anisole and some related aromatic ethers on the interlamellar surfaces of Cu(II) hectorite has been investigated by i.r. and e.s.r, spectroscopy. In addition to physical adsorp- tion, anisole forms two distinct types of Cu(II) complexes which are analogous to the type 1 and II species previously reported for benzene-Cu(II) smectite systems. These complexes can be trans- formed to type I and II complexes of 4,4'-dimethoxybiphenyl. Possible mechanisms are proposed for the oxidation process. Butyl phenyl ether formed a type II complex with Cu(II)-hectorite, no dimerization reaction was noted in this system. Phenyl ether and benzyl methyl ether form a type I ~r complex with Cu(II)-hectorite. type II analog was noted. E.S.R. spectra of each of the type II ether-Cu(II)-hectorite systems showed a sing/e, narrow band with g near the value expected for a "free spinning" electron. The type I phenyl ether and benzyl methyl ether complexes also exhibited this e.s.r, band. Ag(I) hectorite adsorbs anisole by forming exclusively a type I complex. Na(I) and Co(II) hectorite adsorb anisole by physical means only, indicating association with the silicate surface.read more

Modified clays for the adsorption of environmental toxicants; binding of chlorophenols to pillared, delaminated, and hydroxy-interlayered smectites
TL;DR: In this paper, the pore structure and surface composition of the modified clay adsorbent, not on surface area alone, was investigated for PCP adsorption in de-laminated clays.

Reactions of polynuclear aromatic hydrocarbons on soil
TL;DR: In this article, the interactions of anthracene with three soils and montmorillonite clay were studied as a function of time and moisture content, and the results suggest that analysis of air-dried or oven-damaged soil samples may be subject to error and that thermal desorption processes for treating soil may cause polymerization on the soil surface.

TL;DR: The NH4+ formed by the protonation process in different environments in the bentonite and nontronite clays are believed to be due to charge site location and its effects on ion hydration as discussed by the authors.
