What are inorganic elements

Inorganic elements refer to chemical elements in nature that do not have hydrocarbons as the main structure. They are widely found in the earth's crust, water, and atmosphere. They are the basic units that constitute inorganic substances. Unlike organic elements (such as carbon, hydrogen, oxygen, etc.), they usually do not participate in the metabolic process of living organisms, but they play an important role in industry, agriculture, medicine and other fields. This article will systematically introduce the classification, characteristics and applications of inorganic elements based on hot topics in the past 10 days.

1. Classification of inorganic elements

Inorganic elements can be divided into the following categories based on their chemical properties and forms of existence:

2. Applications of inorganic elements in recent hot topics

1.Lithium element in new energy batteries: In the past 10 days, global lithium price fluctuations have triggered heated discussions. Lithium (Li), as a light metal, is the core material of electric vehicle batteries. Its supply and demand relationship directly affects the development of the new energy industry.

2.Silicon element in the semiconductor industry: The U.S. chip export control policy towards China continues to ferment. Silicon (Si), as a basic semiconductor material, has a purity requirement of up to 99.9999%, making it a key resource for technological competition.

3.Rare earth elements in the field of environmental protection: The first anniversary of the establishment of China Rare Earth Group has attracted attention. Rare earth elements such as lanthanum (La) and cerium (Ce) are indispensable in wind turbines and energy-saving lamps, and their green mining technology has become a hot topic.

3. Biological significance of inorganic elements

4. Progress in detection technology of inorganic elements

1.X-ray fluorescence spectrometry (XRF): It can quickly detect the content of multiple elements without destroying the sample. It has recently made new breakthroughs in the analysis of archaeological artifacts.

2.Inductively coupled plasma mass spectrometry (ICP-MS): Can detect trace elements at ppt level (one part per trillion), becoming an important tool for environmental monitoring.

3.Atomic Absorption Spectroscopy (AAS): Precise quantitative analysis of specific elements, recently widely used in the field of food safety testing.

5. Safety management of inorganic elements

Heavy metal pollution incidents have been reported in many places recently. Special attention should be paid to the following high-risk elements:

Conclusion

Inorganic elements are both the cornerstone of modern civilization and a potential threat to environmental health. Recent hot events in the fields of new energy, semiconductors, and environmental protection have shown that the scientific utilization of inorganic elements requires both technological innovation and standardized management. Understanding its characteristics and applications can help us better respond to resource challenges and environmental risks.
