| Abstract | ||
| Direct intercalation of 4-Chlorophenoxyacetate into ZLH interlayer was obtained by reacting ZnO with 4-Chlorophenoxyacetic acid. The resulting Nanohybrid material is white needle like-crystals with two phases at 21.25. and 18.69 Å respectively. This was characterized using XRD. SEM and TEM to show a fibrous nonohybrid structure. The controlled release study showed that within 2000 min. the accumulation of 4-Chlorophenoxyacetate is 94% and t ½ value of 990 min. That is an indication, ZnO can be used to study the controlled release delivery of herbicide active molecules. | ||
