Effect of pH

Biodegradable “green” and safe substitutes to minimize environmental and health risks are drawing extensive attention for research interest. This research aims to create a water-soluble cationic starch-grafted biodegradable polymer that can be used as a flocculant. As polymers are strong molecules that carry charges, they are effective flocculants. Saturated polymer chains do not change the pH value on adding to wastewater.

CuO nanoparticles were synthesized by alcohol-assisted hydrothermal method at various pH values, using sodium hydroxide as a precursor for pH control. The chemical composition, morphological and structural properties of the obtained CuO nanoparticles were investigated by the Raman and energy-dispersive X-ray spectroscopies, the field-emission scanning electron microscopy, and the X-ray diffraction.

In this work, TiO2-doped carbon aerogel (TiO2/CA) was synthesized from sugarcane bagasse hydrothermal, freezedrying, and carbonization methods. The effects of the calcination temperatures of 400, 500, 600, 700, and 800 oC were also evaluated. The obtained TiO2/CA exhibits an ultralow density (0.021-0.032 g/cm3 ) and porosity of more than 97 %. The asprepared TiO2/CA was applied in photodegradation of methylene blue (MB) with the effects of dose sample and pH were also investigated.

In this paper, we discuss the efficiency of using a Fe2V4O13 catalyst in a heterogeneous Fenton-like process for the degradation and mineralization of Ind. We examined various factors that influence the reaction, such as the initial pH of the reaction mixture, the initial concentration of hydrogen peroxide, the amount of the Fe2V4O13 catalyst, and the reaction temperature was investigated.

The silver nanoparticles are synthesized by the green method using Salix semi-solid extract. Fresh leaves are prepared in a semi-solid extract form that retains active substances and can be preserved for a long time. The parameters of the synthesis process are optimized by examining the effects of pH, Salix semi-solid extract concentrations of extract and AgNO3 concentrations through the UV-Vis absorption spectrum of synthetic particulate solutions.
