Figure-1. Scanning electorn microscopy (SEM) images of: a-f before adsorption:(a) different types of particles with the unequal distribution; (b) various sizes of the particles; (c-d) Cluster of particles in crystalline nature and Kinks, aberration, different types of particles with large pore sizes; (e) the existence of Internal pores, high porosity, heterogeneous surface and White/grey protrusions in the crystalline structure indicate the particle growth; (f) Various shaped particles and Spherical rod like structures; g-i after adsorption: (g-h) Pore coverage by Arsenic molecules and layer formation showing the iron ore’s ability to absorb arsenic molecules; (i) Rod like structure sticking on to the globular particles and settling of Arsenic particles into the pores
