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

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

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

Chemical Screening of Metabolites Profile from Romanian Tuber spp.

Truffles are the rarest species and appreciated species of edible fungi and are well-known for their distinctive aroma and high nutrient content. However, their chemical composition largely depends on the particularities of their grown environment. Recently, various studies investigate the phytoconstituents content of different species of truffles. However, this research is still very limited for Romanian truffles. This study reports the first complete metabolites profiles identification based on gas chromatography-mass spectrometry (GC-MS) and electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-QTOF-MS) of two different types of Romania truffles: Tuber magnatum pico and Tuber brumale. In mass spectra (MS) in positive mode, over 100 metabolites were identified from 14 secondary metabolites categories: amino acids, terpenes, alkaloids, flavonoids, organic acids, fatty acids, phenolic acids, sulfur compounds, sterols, hydrocarbons, etc. Additionally, the biological activity of these secondary metabolite classes was discussed
