N-substituted benzothiazolium compounds are potential chemicals for pesticides and herbicides production. In this way they are able to contaminate the soil as well as earth's water. On the basis of cation exchange reaction mechanism is mineral montmorillonite able to adsorb benzothiazolium compounds from their aqueous solutions and in this manner to prevent their polluting activity. In this interaction layered clay-organocomplexes are formed exhibiting mostly disordered structure with irrational sequence of 001 spacing. Chemical and steric characteristics of organic adsorbates influenced the extent of the retention as well as the stability of the organocomplex formed. |
