Abstract - Water is vital for life, plays a crucial role in the ecosystem, and is highly sought after due to its limited availability. The waste water from dye industries poses significant environmental challenges due to the presence of high concentrations of synthetic dyes and chemicals, which can adversely affect aquatic ecosystems and human health. This project investigates the effectiveness of three adsorbents, such as the banana trunk powder, biochar and rice husk ash, for removing dyes from waste water. The selection of these adsorbents was based on their affordability, accessibility and possible adsorption abilities. The efficiency of these adsorbents is evaluated via their adsorption onto activated carbon, which is produced through the chemical activation of these adsorbents in a hot air oven. Tests for pH, turbidity and hardness were used to assess the purity of the treated water. The study aims to evaluate how effectively three adsorbents, banana trunk powder, biochar, and rice husk ash, remove dyes and to identify the most efficient adsorbent for achieving optimal performance.

Key Words: Adsorption, Hot Air Oven, Banana Trunk Powder, Biochar, Rice Husk Ash, Dyes

What is DOI

DOI:

A DOI will help Author(s) easily locate a document from your citation. Think of it like a Social Security number for the article you're citing — it will always refer to that article, and only that one. While a web address (URL) might change, the DOI will never change.

Where can i find DOI:

In IJSREM journal articles, the DOI will be printed with the article itself, usually on the footer of the page
If the DOI isn't included in the article, look it up on the website CrossRef.org (use the "Search Metadata" option) to check for an assigned DOI.

Benefits:

Allows for a quick and precise search.
Article can always be located.
Persistent link to its location on the Internet.
Easier identification of published articles even if the metadata URL is changed.
Aid in citation tracking, ensuring a researcher has accurate metrics on how and where their research outputs are being used or referenced.
