What is the difference between Phytoextraction and rhizofiltration?

What is the difference between Phytoextraction and rhizofiltration?

The major difference between rhizofiltration and phytoextraction is that rhizofiltration is used for treatment in aquatic environments, while phytoextraction deals with soil remediation.

Which plants is used for rhizofiltration?

A few examples of plants that are employed for rhizofiltration are sunflower, tobacco, spinach, rye and Indian mustard. Plant species besides hyperaccumulators can also be used, as the heavy metals need not be translocated to the shoots (Henry, 2000).

How does rhizofiltration work?

Rhizofiltration refers to the use of plant roots to absorb, concentrate, and precipitate toxic metals from contaminated groundwater. Initially, suitable plants with stable root systems are supplied with contaminated water to acclimate the plants.

What do you mean by Rhizofiltration?

What does Phytostimulation mean?

Phytostimulation, also referred to as enhanced rhizosphere biodegradation, rhizodegradation, or plant-assisted bioremediation/degradation, is the breakdown of organic contaminants in the soil via enhanced microbial activity in the plant root zone or rhizosphere.

What is the meaning of Phytovolatilization?

Phytovolatilization refers to the uptake and transpiration of contaminants, primarily organic compounds, by plants. The contaminant, present in the water taken up by the plant, passes through the plant or is modified by the plant, and is released to the atmosphere (evaporates or vaporizes).

How do you dispose of plants after phytoremediation?

After the plants have been allowed to grow for several weeks or months, they are harvested and either incinerated or composted to recycle the metals. This procedure may be repeated as necessary to bring soil contaminant levels down to allowable limits.

Can plant roots filter polluted water?

Summary: Plant roots enmeshed in layers of discarded materials inside upright pipes can purify dirty water from a washing machine, making it fit for growing vegetables and flushing toilets, according to horticulturists.

What is Rhizodegradation?

Rhizodegradation, sometimes called phytostimulation, rhizosphere biodegradation or plant assisted bioremediation/degradation, is the enhanced breakdown of a contaminant by increasing the bioactivity using the plant rhizosphere environment to stimulate the microbial populations [26].
