After filtration, the glomerular filtrate acidified to solution to orange-red, longer filter will filter out solids, 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, will filtrate to assume the orange red the acidification 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 dec

After filtering, acidification to landfill leachate solution is orange-red, 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.
