Silicate Sample

Purpose: Different compositions of copper oxide (CuO)-doped calcium silicate clusters wereused to treat the cancer cells.Methods: The influence of CuO content on the morphology, drug delivering ability,physicochemical properties and cytotoxicity was investigated.Results: The microcrystalline structure revealed the decrement of the size from (20-36 nm) to(5-7 nm) depending on the copper content percentages. Drug delivering ability of doxycyclinehyclate (Dox) was down regulated from 58% to 28%in the presence of the CuO. The inclusionof CuO and Dox didn’t show any remarkable changes on the physicochemical properties of theCuO-doped calcium silicate nanoparticles.Conclusion: The CuO-doped calcium silicate sample (5 weight %) exhibited great cytotoxicityagainst the tested cell lines compared to the CuO-free sample. CuO-doped materials displayedsignificant anticancer effect; this sheds light on its implication in the treatment of cancer.

Silicate Sample

The silica, one of the by-products of fluorine industry, contains soluble fluoride which is harmful to the environment. Therefore, a study on fixing soluble fluoride was conducted by hydrothermal method with the silica as raw material and adding hydrated lime (HL), and the nanowires-reticulated calcium silicate with high specific surface area up to 143.8m2/g was prepared at the same time. The prepared calcium silicate was used as adsorbent in the experiments of phosphorus (P) adsorption from aqueous solution, the adsorption capacity, adsorption rate and P removability were characterized. The results show that the preparation conditions affect distinctly the adsorption performances of calcium silicate, especially, the dosage Ca/Si molar ratio. For the optimized calcium silicate sample, the total P adsorption capacity is 125.7mg/g and the exchange rate of Ca2+reaches 95.8%, the P residual concentration is only 0.3mg/L, the saturated adsorption time is 3900 min, when the simulation solution with P concentration of 100 mg/L is treated. The P residual concentration is only 0.1mg/L for the simulation solution of 56.12mg/L.
