Preface
In order to implement the Environmental Protection Law of the People's Republic of China and the Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Wastes,
Protect the environment, protect human health, regulate the solid waste of 22 kinds of metal elements of the determination method, the development of this standard.
This standard specifies the inductively coupled plasma emission of 22 metal elements in the determination of solid waste and solid waste leachate
Spectroscopy.
This standard is the first release.
Appendix A to this standard is a normative appendix, Appendix B, Appendix C, Appendix D and Appendix E are informative.
This standard is organized by the Ministry of Environmental Protection Science and Technology Standards Division.
The main drafting unit of this standard. Jiangsu Province Environmental Monitoring Center.
The standard verification unit. Nanjing Environmental Monitoring Center Station, Zhejiang Province Environmental Monitoring Center, Shanghai Environmental Monitoring Center
Station, Changzhou City Environmental Monitoring Center Station, Ma On Shan City Environmental Monitoring Center Station, Lianyungang City Environmental Monitoring Center Station.
This standard is approved by the Ministry of Environmental Protection on February 1,.2016.
This standard has been implemented since March 1,.2016.
This standard is explained by the Ministry of Environmental Protection.
Determination of 22 Kinds of Metal Elements in Solid Waste
Inductively Coupled Plasma Atomic Emission Spectrometry
Warning. The use of perchloric acid, nitric acid, hydrogen peroxide in the experiment is highly oxidizing and corrosive, hydrochloric acid, hydrofluoric acid
Strong volatile and corrosive, the operation should be required to wear protective equipment, solution preparation and sample pretreatment process should be in the process
Do not operate in a fume hood.
1 Scope of application
This standard specifies the determination of 22 kinds of metal elements in solid waste and solid waste leachate inductive coupling plasma emission
Spectroscopy.
This standard applies to the solid waste and solid waste leaching solution of silver (Ag), aluminum (Al), barium (Ba), beryllium (Be),
Calcium (Ca), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), potassium (K), magnesium (Mg)
Manganese (Mn), sodium (Na), nickel (Ni), lead (Pb), strontium (Sr), titanium (Ti), vanadium (V), zinc (Zn)
Thallium (Tl), antimony (Sb) and other 22 kinds of metal elements. If verified, this standard may also apply to other trace amounts of gold
Determination of elements.
The amount of solid waste sample is 0.25 g. When the volume of the fixed volume is 25.0 ml, the detection limit of 22 kinds of metal elements is
0.04 mg/kg ~ 8.9 mg/kg, the determination of the lower limit of 0.16 mg/kg ~ 35.6 mg/kg. 22 kinds of metal e
