Materials with improved adsorbent properties, for retaining Cd2+ and Ni2+ from wastewater

In the most cases, wastewater contains both heavy metals in different concentrations and a number of other organic pollutants. Treating wastewater to remove and, if possible, recover heavy metals is vital for the entire food chain. To achieve this goal, we have designed new materials with improved absorption properties. Thus, we used some recyclable wastes such as power plant ash and eggshell together with zeolites and iron oxides, especially magnetite. The characterization of the new material, designed to retain heavy metals from waste water was done by analytical techniques such as SEM/EDAX, FT-IR, BET, AAS etc

Modern adsorbents for heavy metals captured from wastewater into the circular economy

Intensive industrialization as a requirement of the development of modern society has harmed the environment with severe repercussions on biodiversity, human health and food security. Special efforts are made to set highly effective methods for environmental remediation in the circular economy

Treating polluted water using innovative materials obtained from the recycling process of some waste

Water is the source of life and the basic element of activities/processes. That is why it is particularly important to depollute polluted water and return it to the industrial and agricultural circuit and, as far as possible, make it potable

Bioactive Molecules Profile from Natural Compounds

Currently, wide world research is focused on sustainable development and the demand for innovative clean technologies, nevertheless natural potential reconsideration could represent a viable solution for the identification and design of new pharmacological agents from renewable resources. The main reason consists of special properties of these natural derivates: immunomodulating activity with continuously perfectible selectivity and efficiency. Plants and herb extracts have been used for centuries as traditional medicines, throughout the entire world. Romanian phytotherapy represents practically a very important part of our traditional knowledge and heritage. Therapeutic properties of plant active principles still continue to be the subject of many researches. In this chapter, an overview of plant bioactive molecules from the perspective of modern phytochemistry is presented. A special part is devoted to a very special medicinal plant, Viscum album, in particular identification of amino acids and thionins from mistletoe
