Ammonia and phosphate, which are present in large quantities waste streams such as livestock manure, key compounds fertilization activities. Their recovery will help close natural cycles take a step forward the framework of circular economy. In this work, lab-scale three-chambered microbial electrolysis cell (MEC) has been operated continuous mode for ammonia phosphate from digested pig slurry ...

arsenic is one of the heavy metals and nearly all its compounds, especially organic compounds, are toxic. the wide spectrum of diseases caused by this element has led to evaluation of the toxicity of different arsenic species and identification of the major natural and anthropogenic pollution sources of it in the nature. mining activities are among the main sources of anthropogenic pollution of...

Geothermal conditions are extremely favourable in Hungary. Thermal water is accessible in 70% of the territory of the country, with a lowest temperature of 30°C. For energetic purposes, it can be utilized in two different ways: for supplying heat or generating electricity. In relation to utilization, one of the most serious problems derives from the chemical composition of thermal water. The pr...

Groundwater is an important resource for domestic use and irrigation in the Yinchuan region of northwest China. However, quality groundwater this declining due to human activities, with adverse effects on health. In order study chemical elements health, health risk drinking was calculated based actual situation China U.S. Environmental Protection Agency (USEPA) model. Moreover, sensitivity cont...

At present, all kinds of municipal solid waste incineration (MSWI) fly ash stabilization technology has been reported and successfully applied in many countries. However, leaching procedures are very different that the technologies lack uniform standard, and it is even impossible to predict the long-term stabilization. Geochemical model can explain the environmental stabilization based on chemi...

Formation of organometallic complexes in soil solution strongly influence metals phytoavailability. However, only few studies deal with the influence of metal speciation both on plant uptake and genotoxicity. In the present study, Vicia faba seedlings were exposed for 6h in controlled hydroponic conditions to 5 μM of lead nitrate alone and chelated to varying degrees by different organic ligand...

The electroanalytical technique Absence of Gradients and Nernstian Equilibrium Stripping (AGNES) has been extended by applying stripping chronopotentiometry (SCP) as the re-oxidation stage in the determination of the free concentration of Zn(2+), Cd(2+) and Pb(2+). This new approach, called AGNES-SCP, has been implemented with screen-printed electrodes (SPE) and the standard Hanging Mercury Dro...

15 The electroanalytical technique Absence of Gradients and Nernstian Equilibrium 16 Stripping (AGNES) has been extended by applying stripping chronopotentiometry 17 (SCP) as the reoxidation stage in the determination of the free concentration of Zn 2+ , 18 Cd 2+ and Pb 2+ . This new approach, called AGNES-SCP, has been implemented with 19 screen-printed electrodes (SPE) and the standard Hangin...

High-temperature hydrothermal activity areas in western Sichuan Province, China are ideal objects for studying deep Earth science, extreme ecological environments, and comprehensive geothermal utilization. To understand the geochemical characteristics of rare elements (REEs) Chaluo hot springs authors analyzed composition fractionation REEs through hydrochemical analysis, REE tests, North Ameri...

The growth of the lithium-ion battery industry requires a secure supply raw materials and appropriate end-of-life management batteries. In almost five years, global cobalt consumption has increased by nearly 30%, driven mainly rechargeable Consequently, several risks have been identified for cobalt, in particular growing demand electric vehicles, which could exceed current production. Therefore...
