1a Institute for Environmental Studies, Department of Chemistry , University of South Florida , Tampa , Florida , USA.
Summary
Electrocoagulation post-treatment effectively removed phosphorus using Octolig® chromatography. This method significantly reduced phosphate concentrations in commercial samples to below 0.05 ppm P.
Area of Science:
- Environmental Chemistry
- Water Treatment Technologies
Background:
- Phosphorus contamination in water poses environmental risks.
- Electrocoagulation is a common method for wastewater treatment.
- Advanced post-treatment methods are needed for efficient phosphorus removal.
Purpose of the Study:
- To evaluate the efficacy of Octolig® column chromatography as a post-treatment for electrocoagulation.
- To assess the removal of phosphorus from commercial water samples with varying concentrations.
Main Methods:
- Column chromatography utilizing Octolig®, a polyethylenimine-functionalized silica material.
- Analysis of two commercial samples with initial phosphorus concentrations of 10.2 ppm and 983 ppm P.
- Post-treatment assessment of phosphorus levels.
Main Results:
- Octolig® chromatography significantly reduced phosphorus concentrations.
- Samples treated with Octolig® showed a reduction to less than 0.05 ppm P.
- The method proved effective for samples with high and moderate initial phosphorus levels.
Conclusions:
- Octolig® column chromatography is a highly effective post-treatment for removing phosphorus after electrocoagulation.
- This technique can achieve ultra-low phosphorus levels, meeting stringent environmental standards.
- The study demonstrates a viable solution for advanced phosphorus remediation in industrial wastewater.

1.5K
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

6.6K
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...
