The materials used in the study included silver nitrate (SRL, Gujarat, India), nutrient agar media, nutrient broth and antibiotic assay media (Himedia, Mumbai, India); ethanol (SLC Chemicals, Delhi, India), Whatman filter paper no. 42. (Axiva, Mumbai, India); and methyl orange (MO) (Loba, Chemie, Gujarat, India) and double distilled water (ddw). All the chemicals were analytical grade except silver nitrate and methyl orange dye (LR grade).
Methyl orange
Manufactured by Loba Chemie
Sourced in India
Methyl orange (MO) is a chemical compound commonly used as a pH indicator in analytical chemistry. It is a water-soluble dye that changes color depending on the pH of the solution, making it useful for determining the acidity or basicity of a sample.

Analytical grades of Nitric and Phosphoric acids were obtained from Panreac Company, Spain. Ammonia solution (32% w/w) of density 0.9g/cm 3 was delivered by Scharlau Company, Spain. The power plant waste y ash (WFA) used in the experiments was obtained from the Rabigh power plant located in Jeddah, Saudi Arabia.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
