“…5(a)) for the TGS sample matches well with earlier reported results [21]. The stretching vibrations of the CH 2 groups known to occur at 3021 and 2986 cm À1 seem to be superimposed on the broad absorption band that corresponds to the stretching vibration of NH 3 + group centered around 3168 cm À1 [22].…”

Potassium Manganese Nickel Sulphate Hexahydrate (KMNSH) crystals have been successfully grown by using traditional slow evaporation method. The empirical formula of KMNNSH is K 2 Mn 0.1 Ni 0.9 (SO 4 ) 2 ·6H 2 O with formula weight 430.7698. KMNNSH crystal revealed monoclinic space group P2(1)/c, a = 6.12(4) Å, b = 12.19(9) Å, c = 8.96(7) Å, α = γ = 90˚, β = 105.3(2), V = 645(1)Å3, Z = 2, Dc = 2.2281 g/cm 3 with deep green color. IR confirms that there is strong interaction between free water molecules. The thermal analysis indicates that the water molecules are present in the KMNNSH crystals. The transmission spectrometry of KMNNSH in the range from UV to near IR wavelengths is reported. Atomic Absorption Spectroscopy also have been studied and discussed.

“…The carbonyl bands in the spectrum of SP were shown The fabrication of ZnSO 4 /SP NCs was identified via FT-IR analysis ( Figure 5). A free SO 4 2− ion has four fundamental vibrations (υ 1 , υ 2 , υ 3 , and υ 4 ), and corresponding peaks have been observed in the spectrum of ZnSO 4 as reported [25]. Additionally, the broad band at 3117 cm −1 may be due to the stretching mode of the water molecules.…”

Fabrication and Characterizations of Hot-Melt Extruded Nanocomposites Based on Zinc Sulfate Monohydrate and Soluplus

Zinc sulfate monohydrate (ZnSO 4 )-loaded nanocomposites (NCs) were fabricated by using a hot-melt extruder (HME) system. Soluplus (SP) was adopted as an amphiphilic polymer matrix for HME processing. The micro-size of ZnSO 4 dispersion was reduced to nano-size by HME processing with the use of SP. ZnSO 4 could be homogeneously dispersed in SP through HME processing. ZnSO 4 /SP NCs with a 75 nm mean diameter, a 0.1 polydispersity index, and a −1 mV zeta potential value were prepared. The physicochemical properties of ZnSO 4 /SP NCs and the existence of SP in ZnSO 4 /SP NCs were further investigated by solid-state studies. Nano-size range of ZnSO 4 /SP NC dispersion was maintained in the simulated gastrointestinal environments (pH 1.2 and 6.8 media). No severe toxicity in intestinal epithelium after oral administration of ZnSO 4 /SP NCs (at 100 mg/kg dose of ZnSO 4 , single dosing) was observed in rats. These results imply that developed ZnSO 4 /SP NC can be used as a promising nano-sized zinc supplement formulation. In addition, developed HME technology can be widely applied to fabricate nanoformulations of inorganic materials.
