Use advice for data set
| When utilizing the dataset for modeling and assessment purposes, ensure all methodology follows best practices for in-situ remediation lifecycle assessment. This includes proper accounting for the production and application of the AHNP2 nanoparticles and the associated energy and material inputs into the system. Attention should be paid to the impact of electrolysis conditions, such as current density and duration, on the properties of the nanoparticles. It is also essential to consider the removal efficiency of the nanoparticles and their fate post-treatment in the environmental impact assessment. |
Technical purpose of product or process
| The process described is used for the production of aluminum hydroxide nanoparticles (AHNP2), which are intended for in-situ groundwater remediation applications. These nanoparticles are designed to adsorb contaminants from groundwater by being directly applied to the contaminated site, hence facilitating the removal of pollutants without the need for pumping out the water. |

Hierarchy level

| The aluminum electrode was dissolved in distilled water with a current density of 195 A/m to prepare AHNP2. The electrolysis process lasted for 2 hours, after which it was stopped and the aluminum hydroxide nanoparticles were allowed to settle at the bottom of the electrochemical reactor. The settled particles (precipitate) were filtered and washed multiple times with distilled water to remove traces of sodium chloride used in the electrochemical cell, in order to increase the conductivity of the electrolyte solution. |
