Kalium permanganat adalah suatu senyawa kimia anorganik yang memiliki rumus KMnO4 dan merupakan garam yang mengandung ion K+ dan MnO4-.. Kalium permanganat larut dalam air dan menghasilkan larutan berwarna merah muda atau ungu Intens.Senyawa ini merupakan suatu agen pengoksidasi yang baik, dimana mangan memiliki bilangan oksidasi +4 sehingga dapat dimanfaatkan dibidang kesehatan maupun industry.Review ini bertujuan untuk menganalisis bentuk dari struktur serta interaksi dalam transport ion Kalium Permanganat. Metode yang digunakan dalam penelitian ini adalah penggunaan aplikasi Chemdraw 15.0 (Komputasi),penelusuran literature dengan Endnote X7, serta perhitungan matematis. Kalium permanganat memiliki struktur kristal ortorombik dengan jarak Mn–O adalah1.62Å dan merupakan larutan elektrolit yang memiliki sifat termokimia yaitu entropi molar standar sebesar 171,7 JK-1mol-1,energi bebas Gibbs sebesar -713,8 kJ/mol,serta entalpi pembentukan standar sebesar -813,4 kJ/mol. Interaksi yang terjadi pada ion KMnO4 dapat diperhatikan melalui beberapa parameter, diantaranya adalah konduktivitas, mobilitas,serta kecepatan hanyut ionnya.Konduktivitas dari KMnO4 dipengaruhi oleh konsentrasi yaitu semakin banyak ion yang ada dalam larutan maka mobilitas ion yang juga berhubungan dengan kecepatan hanyut dalam larutan akan semakin berkurang sehingga nilai konduktivitas akan menurun. Mobilitas ion K+ yaitu 7,6 10-8m2s-1V-1, serta kecepatan hanyut KMnO4 sebesar 0,33 V/cm. Berdasrkan metoda komputasi dengan ChemOffice 3D, energi total yang dibutuhkan KMnO4 untuk bergerak sebesar 680.5699 kcal/mol pada suhu 300 K dengan RMS gradient yaitu 33.114.

“…Currently, the hot water extraction method, enzyme-assisted extraction, the lye extraction method, the ultrasonic-assisted method, and the microwave-assisted method are frequently used to extract plant polysaccharides ( 16 , 20 – 22 ). Aqueous two-phase system (ATPS) is a new extraction technology developed in recent years, which has the advantages of simple operation, mild conditions, and environmental protection ( 23 ).…”

IntroductionArctium lappa L. root has high nutritional and medicinal values and has been identified as a healthy food raw material by the Ministry of Health of the People's Republic of China.MethodsIn the present study, an aqueous two-phase system (ATPS) of polyethylene glycol (PEG)-(NH4)2SO4 was used to extract Arctium lappa L. polysaccharides (ALPs) from the Arctium lappa L. roots, the optimal extraction conditions of crude ALPs were optimized by using the single-factor experiment and response surface methodology. The structure and composition of ALPs were determined by fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and high-performance liquid chromatography (HPLC). At the same time, the antioxidant activity of ALPs was investigated by in vitro antioxidant experiment.ResultsThe optimized extraction parameters for extraction ALPs were as follows: the PEG relative molecular weight of 6,000, a quality fraction of PEG 25%, a quality fraction of (NH4)2SO4 18%, and an extraction temperature of 80°C. Under these conditions, the extraction rate of ALPs could reach 28.83%. FTIR, SEM and HPLC results showed that ALPs were typical acidic heteropolysaccharides and had uneven particle size distribution, an irregular shape, and a rough surface. The ALPs were chiefly composed of glucose, rhamnose, arabinose, and galactose with a molar ratio of 70.19:10.95:11.16:6.90. In addition, the ALPs had intense antioxidant activity in vitro with IC50 values in the ·OH radical (1.732 mg/ml), DPPH radical (0.29 mg/ml), and superoxide anion (0.15 mg/ml) scavenging abilities.DiscussionThe results showed that ATPS was an efficient method to extract polysaccharides and could be used for the extraction of other polysaccharides. These results indicated that ALPs had great prospects as a functional food and could be exploited in multiple fields.

Wheat Biocomposite Extraction, Structure, Properties and Characterization: A Review

et al. 2021

View full text Add to dashboard Cite

Biocomposite materials create a huge opportunity for a healthy and safe environment by replacing artificial plastic and materials with natural ingredients in a variety of applications. Furniture, construction materials, insulation, and packaging, as well as medical devices, can all benefit from biocomposite materials. Wheat is one of the world’s most widely cultivated crops. Due to its mechanical and physical properties, wheat starch, gluten, and fiber are vital in the biopolymer industry. Glycerol as a plasticizer considerably increased the elongation and water vapor permeability of wheat films. Wheat fiber developed mechanical and thermal properties as a result of various matrices; wheat gluten is water insoluble, elastic, non-toxic, and biodegradable, making it useful in biocomposite materials. This study looked at the feasibility of using wheat plant components such as wheat, gluten, and fiber in the biocomposite material industry.
