After filtration, glomerular filtrate solution was acidified to petition the solid orange-red, longer filter leaching, solid wash with water, ether, and a khaki-colored solid, soluble in water in the solid NH3 of colorization, activated carbon filtration, and a white solid.

After the filtration, filtrates is acidified, assumes the orange red to the solution, again filters the solid filters out, the solid uses the laundering, the ether to wash, results in the brown color solid, dissolves this solid in the water moves in NH3 the nature, the activated carbon decolorizes,

After filtering, landfill leachate by acidification, showing orange-red to a solution, and then filter filters out solids, solid water wash, ether wash khaki solid, the solid is soluble in water in NH3 tonality, active carbon decoloration, filtering, white solid.
