Particle size and metal distributions in anaerobically digested pig slurry [PDF]

open access: yes, 2008
Particle size distribution and trace element patterns were studied in a full-scale anaerobic digestion plant treating pig slurry. Mass balance was established for major (N, P, K, Ca, Fe, Mg and S) and minor (Al, Cu, Mn and Zn) elements.

Investigation of Adsorption of Cu (II) Heavy Metal with Bentonite

open access: yesBitlis Eren Üniversitesi Fen Bilimleri Dergisi, 2018
In this study, adsorption of undesirable copper (II) ion with bentonite in industrial wastewater was investigated at different temperature, pH and time intervals. Adsorption experiments were started with an adsorbent amount of 0.5 grams. Optimum pH determination experiments were carried out in the first stage of the adsorption experiments.

Comparing metals adsorption by carbon adsorbents: evaluating absorption properties of different carbon adsorbents [PDF]

open access: yes, 2012
Pollution of the aquatic environment by heavy metals has detrimental effect on living species. In this work, novel carbon nano-materials (CNM) and commercial granular activated carbon (GAC) adsorbents were evaluated for removal of heavy metal matrix (Cu,

Adsorption of Lead, manganese, and copper onto biochar in landfill leachate: implication of non-linear regression analysis

open access: yesSustainable Environment Research, 2020
The feasibility of using wood-derived biochar (BC) to remove Pb, Mn, and Cu from landfill leachate was investigated and modeled in this study. BC was produced under the pyrolytic temperature of 740 °C.

Adsorption of heavy metals by road deposited solids

open access: yes, 2012
The research study discussed in the paper investigated the adsorption/desorption behaviour of heavy metals commonly deposited on urban road surfaces, namely, Zn, Cu, Cr and Pb for different particle size ranges of solids.

Heavy metals in paddy fields in Taiwan: chemical behavior in soil and uptake by brown rice

open access: yes, 2009
Levels of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) were measured in 19 individual paddy fields in Taiwan. Total, reactive, and available metal levels were measured using Aqua Regia, 0.43 N HNO3, 0.1 M HCl, 0.05 M ...
