Introduction

The increasing levels of heavy metal pollution, particularly copper ions (Cu²⁺), pose a significant threat to human health and the environment. In this context, the development of effective and environmentally friendly adsorbents is crucial for mitigating this issue. Chitosan glutaraldehyde, a derivative of chitin, has emerged as a promising adsorbent due to its biocompatible and biodegradable properties. This article discusses the provision and characterization of chitosan glutaraldehyde as an adsorbent to determine the level of Cu metal ions using atomic absorption spectrophotometry (SSA).

Preparation of Chitosan Glutaraldehyde Adsorbent

The preparation of chitosan glutaraldehyde adsorbent involves several steps. Initially, chitosan granules are prepared by dissolving chitosan in dilute acetic acid and then condensing it with sodium hydroxide. The resulting chitosan granules are then mixed with a 2.5% glutaraldehyde solution and acetone, before being dried to obtain a cross-linked glutaraldehyde chitosan (cross-linked). This cross-linking process increases the stability and capacity of chitosan adsorption.

Adsorption Process

The adsorption process involves mixing 2 grams of glutaraldehyde chitosan with 20 ml of copper metal solution (Cu²⁺) with a concentration of 0.2 mg/l. The mixture is stirred for 10 minutes and left to allow the adsorption process to take place. After the adsorption process, the upper layer is taken and measured using SSA. The measurement results show that the absorption rate of copper metal ions (Cu²⁺) reaches 73%.

Characterization of Chitosan Glutaraldehyde Adsorbent

The provision of chitosan glutaraldehyde as an adsorbent offers an innovative approach in overcoming the problem of heavy metal pollution, especially copper ions. Chitosan, a derivative of chitin, is known to have biocompatible and biodegradable properties, making it an environmentally friendly choice in the adsorption process. The process of cross-linking glutaraldehyde involves a significant cross-binding, which increases the stability and capacity of chitosan adsorption.

Glutaraldehyde functions as a cross-binding agent, increasing the surface area and giving more active sites to chitosan granules. This allows more metal ions to be bound to the surface of the adsorbent, thereby increasing efficiency in reducing levels of metal ions in the solution. The absorption result of 73% shows that chitosan glutaraldehyde is an effective ingredient to reduce levels of Cu²⁺ ions.

Implications and Future Research Directions

The use of chitosan glutaraldehyde as an adsorbent has positive implications in the field of waste treatment, where the use of natural materials can reduce the environmental impact of industrial processes. Further research is needed to explore variations in concentration, pH, and contact time to maximize the potential of adsorption. Additionally, the characterization of glutaraldehyde chitosan after the adsorption process is essential to understand changes in the physical and chemical properties that occur.

Conclusion

In conclusion, the provision and characterization of chitosan glutaraldehyde as an adsorbent to determine the level of Cu metal ions using SSA has shown promising results. The use of chitosan glutaraldehyde as an adsorbent offers an innovative approach in overcoming the problem of heavy metal pollution, especially copper ions. Further research is needed to explore the potential of chitosan glutaraldehyde in waste treatment and other applications.
