The Relationship between pH and Heavy Metal Ion Sorption by Algal Biomass

open access: yesAdsorption Science & Technology, 2003
The relationship between pH and heavy metal ion sorption by the biomass of two algal species was studied under controlled experimental conditions. It was observed that increasing heavy metal ion sorption by algal biomass with pH mainly arose from a ...

Microfabricated heavy metal ion sensor

open access: yesSensors and Actuators B: Chemical, 1995
Abstract A novel microfabricated electrochemical sensor has been developed for the detection and measurement of heavy metal ions in aqueous media. The sensor consists of a silicon substrate, on which is fabricated an electrically interconnected, but diffusionally isolated, array of thin-film iridium microelectrodes upon which a thin film of mercury ...

Wastewater Treatment from Heavy Metal Ions

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract The article is devoted to the sorption treatment of industrial effluents, which contain heavy metal ions (HMI) by the natural clay mineral kaolinite - an activated adsorbent. The main sources of HMI receipts are revealed - industrial and agricultural production. The influence of heavy metals on human health is considered.

Study on the physical and chemical properties of lead passivating agent in soil

open access: yesScientific Reports, 2023
With the rapid development of industry, heavy metal pollution has seriously damaged the health of soil, and heavy metals spread through the food chain, posing a threat to human health. The firm existence of heavy metals in soil under earthy conditions is

Experimental study on solidification/stabilization of heavy metal lead and chromium sludge solidified by cement-based materials [PDF]

open access: yesMATEC Web of Conferences, 2023
To explore the strength change law and solidification mechanism of cement solidified heavy metal lead and chromium contaminated soil, ordinary Portland cement (OPC) and magnesium phosphate cement (MPC) were used for solidification/stabilization treatment.

Spin dynamics of $Yb Rh_2 Si_2$ observed by Electron Spin Resonance [PDF]

open access: yes, 2006
Below the Kondo temperature $T_{\rm K}$ electron spin resonance (ESR) usually is not observable from the Kondo-ion itself because the characteristic spin fluctuation energy results in a huge width of the ESR line. The heavy fermion metal YbRh$_{2}$Si$_{2}

Functionalized sepiolite for heavy metal ions adsorption

open access: yesDesalination, 2008
Abstract Surface modification of clays has become increasingly important due to the practical applications of clays such as fillers and adsorbents. The surface modification of sepiolite with [3-(2-aminoethylamino)propyl]trimethoxysilane has been employed. The modified sepiolite surface was investigated by FTIR, XRD and DTA/TG analysis.

Pyridine Derivatives as Fluorescent Sensors for Cations

open access: yesChemistry Proceedings, 2023
A fluorescence grating sensor based on a pyridine derivative was synthesized. The results showed that it can rapidly identify and detect toxic heavy metal ions, such as Cr2+, Hg2+, Ni2+ and Co2+.
