NOVELTY - Controlling release of heavy metals from domestic garbage involves crushing solid waste, and treated crushed product with graphene sieve of diameter 0.5-20 mu m. Graphene sieve are made up of graphene oxide. Specific surface area and density of graphene sieve is 40-60m2/g and 2.25g/cm3. Garbage contains sulfate, nitrate, chloride, ammonium, magnesium, calcium, potassium and sodium in a concentration of 14.96, 6.54, 1.68, 3.71, 0.82, 1.38, 0.64 and 0.78mg respectively. Obtained product is cured at 18-25 degrees C at 35-65% relative humidity for 30 days. USE - Method for controlling release of heavy metals from domestic garbage (claimed). ADVANTAGE - The method enables to reduce concentration of cadmium and copper by 19.2% and 72.4% respectively. DETAILED DESCRIPTION - Controlling release of heavy metals from domestic garbage involves crushing solid waste, and treated crushed product with graphene sieve of diameter 0.5-20 mu m. Graphene sieve are made up of graphene oxide. Specific surface area and density of graphene sieve is 40-60m2/g and 2.25g/cm3.

Obtained product is cured at 18-25 degrees C at 35-65% relative humidity for 30 days. Obtained product is tested by absorption spectrophotometer to determine concentration of heavy metals such as copper, lead and cadmium.
