The classical forerunner of metallizable anthraquinone dyes was alizarin, which produced the aluminum complex dye Turkey Red by the mordanting process (Scheme 1). The KOH is then drained off and the fetuses are placed in 0.5% KOH and alizarin red solution (25 mg L) for 24 h. The staining solution is then poured off and replaced with 25% glycerin for 1 week and is then placed in 1:1 solution of 70% ethanol/99.5 glycerin, and the fetal skeleton can remain in this solution for evaluation and storage. chains, mordants such as alum, and natural dyes such as alizarin. Onion's scale (Allium cepa) natural dye The enzymatic process is considered the best since acidic or basic hydrolysis leads to the formation of a mutagenic compound called lucidin (Bechtold and Mussak, 2009; Chenciner, 2000). L−1 was fixed, and the reaction temperature was adjusted to 20°C. It is considered an incredibly vibrant color that is also somewhat grim due to its similarity to the color of oxygenated blood. Madder was formerly used in large quantities for dyeing textiles and is still the color for French military cloth. The alcohol is then drained off; the fetuses are rinsed with tap water, drained, and then placed in a 2% potassium hydroxide (KOH) solution for 24 h in rats and up to 48 hours in rabbits. dyes are extensively employed in the textile industries due to their wide range of color shades and ease of application. These reagents tend to form different complexes with Al, sometimes leading to good sensitivity of the method (nanogram per milliliter detection limits using alizarine violet N) or increasing its selectivity, thus allowing aluminum determination in complex matrices such as cement (quinizarin), plant digest (chrome azurol S), milk (alizarin), and botanical samples (Eriochrome cyanine R). It was observed from the concentration study that the amount of dye adsorbed per unit mass of the adsorbent increased with increase in dye concentration. toward dil.
