The types of microplastics, heavy metals, and adsorption environments control the microplastic adsorption capacity of heavy metals

Environmental Science and Pollution Research, 2023
Anthropogenic development has released large amounts of microplastics (MPs), which are carriers of migratory heavy metals, into the environment, and heavy metal adsorption by MPs may have strong combined toxic effects on ecosystems. However, until now, a comprehensive understanding of the factors influencing these adsorption capacities of MPs has been ...

Macrophyte biomass productivity for heavy metal adsorption

Journal of Environmental Management, 2021
The search for low cost adsorbents that have metal-binding capacities has intensified in the last decades. Some natural aquatic macrophytes have been studied as adsorbents to remove heavy metals. Macrophytes ease to propagate converts them into plague for many ecosystems while they are also considered by some activities as a residue; therefore its ...

Competitive Adsorption Behavior of Heavy Metals on Kaolinite

Journal of Colloid and Interface Science, 2005
Polluted and contaminated soils can often contain more than one heavy metal species. It is possible that the behavior of a particular metal species in a soil system will be affected by the presence of other metals. In this study we have investigated the adsorption of Cd(II), Cu(II), Pb(II), and Zn(II) onto kaolinite in single- and multi-element systems

Adsorption Behavior of Heavy Metals on Biomaterials

Journal of Agricultural and Food Chemistry, 2004
We have investigated adsorption of Cd(II) and Pb(II) at pH 2-6.7 onto the biomaterials chitosan, coffee, green tea, tea, yuzu, aloe, and Japanese coarse tea, and onto the inorganic adsorbents, activated carbon and zeolite. High adsorptive capabilities were observed for all of the biomaterials at pH 4 and 6.7.

Adsorption of heavy metals on kaolinite and montmorillonite: a review

Physical Chemistry Chemical Physics, 2012
The process of adsorption is considered to be one of the best water treatment technologies around the world. Different heavy metals, due to their toxic and hazardous nature, are possibly the most widespread groundwater contaminants imposing a serious threat to human health.

Adsorption of heavy metal ions by immobilized phytic acid

Applied Biochemistry and Biotechnology, 1997
Phytic acid (myoinositol hexaphosphate) or its calcium salt, phytate, is an important plant constituent. It accounts for up to 85% of total phosphorus in cereals and legumes. Phytic acid has 12 replaceable protons in the phytic molecule, rendering it the ability to complex with multivalent cations and positively charged proteins. Poly 4-vinyl pyridine (

Adsorption of Heavy Metals–A Review

Materials Today: Proceedings, 2019
Abstract Many researchers have used coal fly ash; rice husk ash, nano material and conducting polymer- as adsorbents to remove water pollutants including Cr, Pb, Hg, Zn, Mn and Cu, heavy metal. The main objective in this study to identify the nano materials used for heavy metal adsorption process effectively.
