Today, with expanding industries, wastewater treatment of them is a global problem. Heavy metal is one of the most common and most dangerous contaminants in waste water that over time, with the strict standards of output, find more effective ways of eliminating them has always been a challenge. New methods, especially in the field of adsorption have achieved promising results in many cases.
Polymers composites are one of the adsorbent for the removal of these contaminants have been considered. In this project Aniline and composites to remove arsenic and chromium were studied. In polymers synthesis factors like type of additives and oxidizing materials strongly effected on morphology of... 

Given the rapid growth of the population and the increasing demand for drinking water, along with the depletion of freshwater resources, the presence of heavy metals such as arsenic, cadmium, mercury, lead, and chromium in water sources is considered a serious threat to public health due to their bioaccumulation properties and potential carcinogenicity. In this study, the process of nanofiltration has been employed to remove these heavy metals. Nanofiltration is recognized as an effective method for water treatment due to its low energy consumption and high efficiency. The primary objective of this research is to enhance the physical and chemical properties of nanofiltration membranes...
