The Role of Calcium in the Calcium Polystyrene Sulfonate and Calcium Stearat Ads: A Study on the Adsorption and Desorption of Tocopherol and Tocotrienol from Hazelnut Oil

Introduction

The adsorption and desorption of tocopherol (TP) and tocotrienol (TT) from methyl esters of hazelnut oil are crucial processes for separating and obtaining these compounds. Tocopherols and tocotrienols are essential nutrients that play a vital role in maintaining human health. They are known for their antioxidant properties, which help protect cells from damage caused by free radicals. However, the separation and purification of these compounds from hazelnut oil can be challenging due to their complex structure and the presence of other impurities.

The Role of Calcium in Adsorbents

Calcium (CA) is a key component of adsorbents, which are materials used to separate and purify substances from a mixture. In this study, we examined the role of calcium in the adsorbent of calcium polystyrene sulfonate (CA-PSS) and calcium stearate (CA-St) in the process of adsorption and desorption of TP and TT from hazelnut oil.

Adsorption and Desorption of Tocopherol and Tocotrienol

Adsorption is the process of attracting and holding onto a substance, while desorption is the process of releasing a substance from an adsorbent. In this study, we used CA-PSS and CA-St as adsorbents to separate and purify TP and TT from hazelnut oil. The results showed that the concentration of CA in the adsorbents had a significant effect on the efficiency of adsorption and desorption.

Effect of Calcium Concentration on Adsorption and Desorption

The results showed that CA-PSS with a CA concentration of 8.60% was able to adsorb TP and TT around 96.7% and 100%, respectively, while the desorption was only 2.1% and 1.1%, respectively. Similarly, CA-PSS with a CA concentration of 6.14% adsorbed TP and TT around 96.7% and 99.10%, respectively, while the desorption was around 2.3% and 1.4%, respectively. On the other hand, CA-St with a CA concentration of 6.00% adsorbed TP and TT around 90.6% and 98.8%, respectively, with desorption of around 2.7% and 2.3%, respectively.

Conclusion

From the results, it can be concluded that a higher CA concentration in adsorbents increases the ability of TP and TT adsorption, but decreases its desorption capabilities. This shows that CA acts as a binding site for TP and TT, so that more CA, more TP and TT can be bound. However, the bond between TP and TT and a stronger CA also makes the desorption process more difficult.

The Role of Hydrocarbon Chain Length

In addition to the CA concentration, the length of the hydrocarbon chain bound by CA also affects the adsorption and desorption process. The longer hydrocarbon chain, such as calcium stearate, increases the ability of TP and TT adsorption, but also reduces its desorption ability. This shows that the hydrophobic interaction between the hydrocarbon chain and TP/TT plays an important role in the adsorption process, while this interaction also inhibits desorption.

Implications of the Study

This finding provides important information about the role of calcium in adsorbents to separate and obtain TP and TT from hazelnut oil. This knowledge can be used to develop more efficient adsorption and desorption strategies to get these compounds with better quality and quantity. The study highlights the importance of CA concentration and hydrocarbon chain length in the adsorption and desorption process, and provides a basis for further research in this area.

Future Directions

Future studies can focus on optimizing the CA concentration and hydrocarbon chain length to improve the efficiency of adsorption and desorption. Additionally, the study can be extended to other types of adsorbents and substrates to explore their potential in separating and purifying TP and TT from hazelnut oil.

Conclusion

In conclusion, the study highlights the importance of CA concentration and hydrocarbon chain length in the adsorption and desorption process of TP and TT from hazelnut oil. The findings provide valuable information for the development of more efficient adsorption and desorption strategies to obtain these compounds with better quality and quantity.
