Summary
Manufactured nanoparticles in water change surface properties based on solution chemistry. Understanding these nanoparticle-water interactions is key for environmental risk assessment.
Area of Science:
- Environmental Science
- Materials Science
- Chemistry
Background:
- Aqueous systems are primary pathways for manufactured nanoparticles into the environment.
- Nanoparticle behavior and hazard in water are critical for environmental and human risk assessment.
- Solid/liquid interface reactions dictate nanoparticle dispersion, behavior, and surface speciation.
Purpose of the Study:
- To review the current scientific understanding of manufactured nanoparticle surface property changes in aqueous solutions.
- To examine how different aqueous solution compositions affect nanoparticle behavior.
- To provide a foundation for assessing environmental risks associated with nanoparticles.
Main Methods:
- Review of general reactions at the nanoparticle/water interface.
- Case-by-case analysis of metal oxides, pure metals, and carbon nanoparticles.
- Consideration of nanoparticle interactions in model and inorganic aqueous solutions.
Main Results:
- Nanoparticle surface properties and behavior are significantly altered by aqueous solution chemistry.
- Reactions at the solid/liquid interface are fundamental to nanoparticle environmental fate.

01:29The Colloidal State
The formation of a colloidal system is exemplified by an aqueous solution containing Cl− ions is introduced to another containing Ag+ ions, resulting in the precipitation of solid AgCl as extremely tiny crystals. Instead of settling out as a filterable precipitate, these crystals remain suspended in the liquid, showcasing a colloidal system.A colloidal system involves colloidal particles within the approximate range of 1 to 1000 nm in at least one dimension, dispersed in a medium called the...
03:22Colloids
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...
01:09Colloidal precipitates
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...
03:18Nuclear Stability
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.
