Analisis Kadar Logam Besi (Fe) Pada Air Minum Dalam Kemasan Menggunakan Metode SSA

Summary

This video provides an in-depth analysis of the iron content in bottled drinking water using Atomic Absorption Spectroscopy (AAS). It begins by discussing the importance of water, its various properties, and quality standards, followed by an exploration of the potential contaminants in water, such as iron. The method of AAS is explained, alongside the equipment and procedure used in the analysis. The results show that the iron levels in bottled water are within the permissible limits set by health regulations, making the water safe for consumption. The presentation concludes with the significance of adhering to water quality standards.

Takeaways

• 😀 Water is a crucial natural resource necessary for life and must be managed wisely for current and future generations.
• 😀 Water has two types of bound water: physically bound and chemically bound, with different methods required to remove each.
• 😀 Good quality drinking water should be clear, colorless, and free from unpleasant taste or odor, with a temperature lower than the air's temperature.
• 😀 The quality of drinking water is classified into four groups in Indonesia, ranging from direct consumption without treatment to industrial uses.
• 😀 Drinking water quality is assessed through physical, chemical, and biological parameters, with a focus on avoiding contaminants like harmful bacteria and toxic chemicals.
• 😀 Water sources are divided into groundwater (shallow and deep) and surface water (from rivers, lakes, and ponds).
• 😀 The Ministry of Health's regulation No. 492/2010 sets the standard for drinking water quality in Indonesia, aiming to protect public health.
• 😀 Water pollution is a significant issue caused by improper waste disposal, industrial activities, and chemicals released into water bodies.
• 😀 Iron is an essential macromineral found in the Earth's crust but can be toxic in excess, especially for children, causing harm to organs like the liver and kidneys.
• 😀 Atomic absorption spectrophotometry (AAS) is used for analyzing iron levels in water by measuring the absorption of specific wavelengths of light by iron atoms.
• 😀 The analysis of iron content in bottled water showed that the concentration of iron was 0.004 mg/L, which is below the permissible limit of 0.3 mg/L set by health regulations, making it safe for consumption.

Q & A

What is the purpose of the video presented in the script?

The purpose of the video is to fulfill an assignment for the course 'Kapita Selekta Kimia Analitik' at Universitas Negeri Padang, discussing the analysis of iron content in bottled drinking water using atomic absorption spectrophotometry.

What are the two main types of water binding discussed in the video?

The two main types of water binding discussed are physically bound water and chemically bound water. Physically bound water can be removed by heating, while chemically bound water includes crystalline water and constitutional water.

What are the five properties of water mentioned in the script?

The five properties of water are: 1) It supports life within a temperature range of 0°C to 100°C; 2) It has a slow temperature change and serves as an excellent heat reservoir; 3) It requires high heat for evaporation; 4) It is a good solvent for various chemicals; 5) It has a high surface tension.

What are the four categories of water quality as per the Indonesian government regulation?

The four categories of water quality according to the Peraturan Pemerintah Republik Indonesia Nomor 20 Tahun 1990 are: 1) Category A (directly drinkable water), 2) Category B (water for bathing and other non-drinking uses), 3) Category C (water for fisheries and livestock), and 4) Category D (water for agriculture, urban industry, and hydropower plants).

What are the three parameters used to assess drinking water quality?

The three parameters used to assess drinking water quality are: 1) Physical and chemical parameters, 2) Biological parameters, and 3) Chemical contamination levels.

What are the sources of water mentioned in the script?

The two main sources of water mentioned are groundwater and surface water. Groundwater includes shallow, deep, and spring water, while surface water is found in rivers, lakes, reservoirs, and swamps.

How is water quality standardized for drinking water in Indonesia?

Water quality for drinking is standardized through the Peraturan Menteri Kesehatan Republik Indonesia Nomor 492 Tahun 2010, which sets the criteria to ensure safe drinking water, safeguarding public health and regulating the processing and distribution of drinking water.

What are the main causes of water pollution as highlighted in the video?

The main causes of water pollution include human ignorance, the discharge of waste water and sewage, industrial activities, and the use of chemicals, all of which can lead to contamination in water bodies.

What is the significance of iron in drinking water and the risks associated with high iron content?

Iron is a macro-mineral found in the Earth's crust and can pose health risks if consumed in excess. High iron levels can cause toxicity, especially in children, and may lead to damage to the stomach, liver, kidneys, and blood vessels.

What is atomic absorption spectrophotometry, and how is it used to analyze iron content?

Atomic absorption spectrophotometry (AAS) is a method used to determine the concentration of metals like iron in a sample by measuring the absorption of light at a specific wavelength by free atoms of the metal. In this analysis, a sample is evaporated, and the absorbed radiation is measured to calculate the iron concentration.

What was the result of the iron concentration analysis in bottled water as mentioned in the script?

The analysis showed that the iron concentration in the bottled drinking water was 0.004 mg/L, which is within the permissible limit of 0.3 mg/L set by the Indonesian Ministry of Health's regulation.
