iron oxide nanoparticles are used in molecular imaging and drug delivery as a
nanoscale magnetic material. Cobalt iron oxide are used for the field of
environment remediation in wastewater treatment. They will study the cobalt
leakage of the coated nanoparticles.  In
this research work, by using high temperature they will synthesize high
crystals of cobalt ferrite nanocrystals. When they will change experimental
conditions then size of particles will vary from 4 to 9 nm. Transmission electron
microscopic (TEM) will display stability of nanocrystals. TEM will show two and
three dimension images of particles. X-ray diffraction and high-resolution
transmission electron microscopic will display high crystalline images of the cobalt
ferrite structure. X-ray diffraction will investigate structural properties and
phase composition of cobalt iron oxide. The atomic composition of nanocrystals
will display elemental analysis of cobalt ferrite. The behavior of magnetic
nanoparticles highly  involves in this
nanocrystals of cobalt iron oxide.

.Dyes are complicated organic compounds which
are used by various industries to colour their products.Water that is released

these dyes are toxic that can cause skin and eye irritation. Therefore, many
