   Ruthenium can be seawater or bittern, which can be partially evaporated to obtain ruthenium in one or more yields. How much is ruthenium per gram? Strontium calcium and potassium can recover protein reagents from the enzymatic degradation of plant fertilizers, animal manure slaughterhouse by-product sewage, sewage sludge garbage fish by-products, and yeast. Ruthenium recycling manufacturers particularly prefer the materials recovered from the waste compost of the grape pressing operation, including seeds and peels of beet and spinach garbage alfalfa, weeds, lint, cotton seed husks and leaves can be treated with ammonium hydroxide before being treated with reagents. The adjustment of the ruthenium solution to a mixture of lignan and protein materials can be used to form a flocculated precipitate of the metal complex, and then tannin is added to convert the precipitate into a more granular state. The precipitation can be stabilized by adding monoammonium phosphate and diammonium phosphate after the precipitating agent. The precipitate is said to be suitable for use as a fertilizer additive. Abstract from the price value per gram of ruthenium in India by treating the above product with a solid adsorbent such as a group metal compound, trace catalysts present in the organic reaction product, such as ruthenium present in the hydroformylation reaction product, can be removed. The periodic table or molecular sieve or ion exchange resin is at a temperature of about room temperature to about one gram and a pressure of about atmospheric pressure to about atmospheric pressure. Many organic reactions involve the use of catalysts, especially metal-containing catalysts..


 
   When using these catalysts that may contain metals in elemental form or as metal components, it is necessary to recover the catalyst or the metals contained therein to make the process economically feasible. When using precious metals, for example, the precious metals of the group of the periodic table include platinum, Palladium, ruthenium, rhodium, iridium or other metals such as gold, silver or other metals, especially due to the high cost of these metals. As mentioned earlier, the loss of the metal must be kept to a minimum in order to keep the total cost of the reaction to the lowest possible point . As an example of the type of organic reaction involving the use of noble metals, hydroformylation reaction can be cited. In this type of reaction, the alkene hydrocarbon can be treated with carbon monoxide and hydrogen in the presence of a rhodium-containing compound. It is used as a catalyst in the process of preparing alcohol in one step. The commercialization of the method of synthesizing alcohols with palladium valence is affected by the difficulties associated with the price of ruthenium recovery. Particular disadvantages that are not conducive to the commercial use of such complex catalysts include the possibility of frequent loss of precious metals under process conditions. The loss of only traces of this precious metal makes the process uneconomical to operate, and the historical trend of ruthenium prices obscures the technical conversion and selectivity obtained when using this metal. Since the unstable ruthenium complex has a tendency to decompose in the distillation apparatus, it is impractical to separate the rhodium catalyst from the alcohol product, especially the high molecular weight alcohol, by a conventional method such as distillation. The ruthenium-containing catalyst can be recovered from the alcohol product of the hydroformylation reaction to a relatively large extent by treating the alcohol with various nitrogen-containing compounds, such as amines, with various compounds including ammonium hydroxide in an aqueous or anhydrous state.


 
   In the case of using an aqueous ammonium hydroxide solution as a treatment agent, the ruthenium complex can be separated from the organic product phase and remains in the water phase. The latter can then be recycled to the hydroformylation zone and used as a catalyst therein, but the liquid product phase will still contain traces of ruthenium, so it is necessary for the manufacturer to recover or substantially reduce the amount of ruthenium still present in the product. Trace amounts of rhodium. As will be shown in more detail below, it has now been discovered that the 2020 ruthenium price can remove relatively large amounts of trace metals present in the organic reaction product by contacting it with a solid adsorbent of the type described in more detail below. The product and the metal are recovered for further use. SUMMARY OF THE INVENTION The present invention relates to a method for recovering trace metals in products from reactions. Ruthenium valence in India. This reaction involves the use of said metals as its catalyst. More particularly, the present invention relates to a method for recovering trace amounts of precious metals that have been used as catalysts for organic reactions. Various organic reactions involve the use of metal-containing catalysts. In many cases, these metal catalysts contain precious metals, which can be retained in the products obtained from specific reactions due to the special properties of the catalysts. One such reaction involves the formation of alcohols. Alcohols are important basic chemical substances widely used in the chemical industry. For example, isopropanol is used to make acetone and acetone is a source of acetic anhydride, diacetone alcohol, methyl isobutyl ketone, etc., or it can be used as a solvent, such as oleoresin resin. The same dodecanol is also called lauryl alcohol. Synthetic detergents, lubricant additives, therefore, the object of the present invention is to provide a method for recovering metals. Another object of the present invention is a method for recovering trace metals present in organic reaction products, wherein the organic reaction is used as a catalyst for the metal. On the one hand, an embodiment of the present invention resides in recovering the product from the reaction. In the trace metal method, the reaction involves using the metal as its catalyst, and the method includes contacting the product with a solid adsorbent selected from the following.
