The Use Of Beads Chitosan-microcrystals Of Alang-alang Cellulose (imperata Cylindrica) As Adsorbents For Lead Ions (Pb2+)
The use of beads chitosan-microcrystals of alang-alang cellulose (imperata cylindrica) as adsorbents for lead ions (Pb2+)
Introduction
Lead pollution (Pb2+) is a serious problem that threatens human health and the environment. Lead can enter the body through food, water, and air, causing various serious diseases such as brain damage, kidney disorders, and disorders of the reproductive system. Therefore, efforts are needed to overcome lead pollution with effective and environmentally friendly solutions. This study examines the potential use of beads chitosan-microcrystals of alang-alang cellulose (imperata cylindrica) as adsorbents for lead ions (Pb2+).
Background
Alang-alang (imperata cylindrica) is a type of grass that is widely available and inexpensive. It has the potential to be converted into effective adsorbent material. Chitosan, a biodegradable polymer, is commonly used as an adsorbent due to its high adsorption capacity and biocompatibility. However, the use of chitosan as an adsorbent has some limitations, such as its low stability and high cost. Therefore, the development of a new adsorbent material that is environmentally friendly, efficient, and stable is necessary.
Making Beads Chitosan-Microcrystal Cellulose Alang-Alang
Chitosan-Microcrystal Beads Cellulose alang-alang is made by mixing chitosan and cellulose microcrystals (MCC) reeds in acetic acid 2% until homogeneous mixed. The mixture is then dropped into 0.5m NaOH solution to form beads. The resulting beads is then washed until neutral and dried. To increase the stability and ability of adsorption, beads chitosan-MCC is crosslinked with glutaraldehyde 0.5% for 24 hours. Crosslinking beads are then washed until neutral and dried.
Characterization of Chitosan-Microcrystal Cellulose Alang-Alang Beads
Characterization of Chitosan-MCC beads is done using several methods, namely:
*** FTIR spectroscopy: *** The results of FTIR analysis indicate the presence of an imina bond (c = n) and the COH group in the chitosan-MCC beads that have been crossed with glutaraldehyde. This shows that the crosslinking process was successfully carried out.
*** Swelling Test: *** Crosslink Chitosan-Mcc Beads shows resistance to various conditions, namely acid solution (5% acetic acid, 5% formic acid), neutral (distilled water), and base (0.5m NaOH).
*** Crosslinking Degree Test: *** The crosslinking degree test results show that the Crosslinking Chitosan-Mcc beads with the addition of 0.3 g Mcc have the highest degree of crosslinking, which is 54.257%.
*** Electron Scanning Microscope (SEM): *** SEM analysis shows the surface of chitosan-MCC beads that are croslinked fine and homogeneous.
The Ability of Adsorption Beads Chitosan-Microcrystal Cellulose Reeds Against Lead Ions (Pb2+)
The adsorption capability test shows that the chitosan-MCC and chitosan-MCC beads that are crosslinked with a ratio of 7: 3 have the highest adsorption capacity of PB2+ ions, which is around ± 97.366% and ± 95.276%. This shows that Beads Chitosan-MCC has good potential as an adsorbent to overcome lead pollution.
Advantages of Beads Chitosan-Microcrystal Cellulose Alang-Alang
*** Environmentally friendly: *** Derived from natural resources that are easily obtained and renewable.
*** Efficient: *** Has a high adsorption ability to lead ions.
