Study of chemical and physical parameters affected on purification of water from inorganic contaminants

Abstract

The ability to remove perchlorate anions was investigated by the adsorption technique in a laboratory scale and by a batch type unit from contaminated aqueous solutions prepared at specific concentrations. The adsorption process was carried out using banana peels, which were chosen as an available, cheap, and lowcost adsorption media. The studied operating conditions in the treatment process were the acidic function, shaking speed, contact time, temperature, in addition to the initial concentration of perchlorate, which ranging from 1-10, 100-400 rpm, 10-180 min, 20-50 ºC, 50-1000 ppb respectively, while the dose of adsorbent media ranged between 0.5-6 g and the particle size ranged from 0-Pan. The experimental results showed that the removal efficiency of perchlorate changes directly with the shaking speed, contact time, particle size and the dose of adsorbent, while it was inversely with the remaining variables for certain levels. Thus, two types of contaminants were disposed of simultaneously in a beneficial, and eco-friendly manner, reaching to Zero Residue Level (ZRL).

Dyes Adsorption from Contaminated Aqueous Solution Using Sylicone Dioxide Nanoparticles Prepared from the Extracted Tree Leaves

“…This can be explained by the saturation of the adsorption sites on the adsorbent material (Abbas and Ibrahim, 2020). At this point, the adsorbent has reached its maximum capacity and is no longer capable of adsorbing additional dye molecules (Abdullah et al, 2023).…”

“…They are available materials that are non-valuable and must be disposed of, in addition to having effective aggregates and a suitable surface area that made them a successful alternative to activated carbon, as well as being materials with appropriate efficiency and good effectiveness in treating pollutants . These materials include banana peels (Abdullah et al, 2023) (Abdulkareem et al, 2023). A wide range of contaminants can be remediated by agricultural and industrials wastes, such as phenols (Ho, 2022), inorganic toxic (Alalwan et al, 2020), heavy metals (Hashem et al, 2021), hardness (Ibrahim et al, 2021), etc.…”
