Abstract
The phytoremediation process for removing hazardous metals, such as Be, Cr, Co, Mn, and Ra, from contaminated soil and/or coal fly ash, e.g. in a landfill, includes growing plants in the soil and/or fly ash; incorporating a root growth inducing auxin in the soil and/or fly ash in the vicinity of the growing plants and subsequently cultivating the plants until a predetermined increase in root mass of the plant roots has occurred. The preferred auxin is 3-4-deoxy-glucosamine, which was found to increase plant root mass by 200% to 800%. An organic synthesis using glucosamine as starting material or a bioengineering process starting with commercial micronized shrimp meal and/or crab meal moistened with water can provide the 3-4-deoxy-glucosamine. Economical embodiments of the process use plants that produce marketable products and recovers valuable metals.
