“…The CMC was obtained as a white powder with a 71.47% yield. This yield is double compared to that reported by Bono et al (2009) (33.15%) for CMC from palm kernel cake; and Huang et al (2017) (64.40%) for CMC from spent tea leaf. The difference in yield could be attributed to the temperature of the reaction, and the concentration of NaOH and carboxymethylating agent.…”

Isolation of cellulose from Screw pine (Pandanus tectorius) leaves and its transformation into cellulose ethers have been successfully conducted. Crystalline cellulose was obtained as a white powder in 40.24% yield from dried Screw pine leaf powder through alkalization with sodium hydroxide followed by bleaching with sodium hypochlorite. The crystalline cellulose was converted to methyl cellulose (MC), carboxymethyl cellulose (CMC), and hydroxypropyl cellulose (HPC) and obtained 94.6%, 71.47%, and 81.54% yields, respectively. The physicochemical properties of MC, CMC, and HPC, such as shape, color, pH, Degree of Substitution (DS), and viscosity meet the standards for application as a food additive. The pH and viscosity of the synthetic cellulose ethers were 7.53-7.60 and 61.98-62.41 cP, respectively. The DS value for MC, CMC, and HPC were 1.680, 0.996, and 0.696, respectively. The study revealed the potential of Screw pine cellulose to obtain food-grade cellulose ethers since the properties of MC, CMC, and HPC agree with food additive criteria.

This work aimed to prepare solid polymer blend electrolytes based on carboxymethyl cellulose (CMC) and carboxymethyl chitosan (CMCh) complexed with lithium acetate (LiCH3COO) for lithium‐ion batteries application. The solid polymer blend electrolytes of LiCH3COO‐complexed CMC/CMCh (50/50) polymer blend electrolyte were prepared by using the casting solution technique, where various weight percentages of LiCH3COO were mixed into CMC/CMCh (50/50) blend as host polymer. Solid polymer blend electrolytes of CMC/CMCh + 30wt% LiCH3COO had the highest ionic conductivity as much as 2.24 × 10−5 S cm−1 among others. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO degraded at temperature interval 256–473°C. Linear sweep voltammetry method shows that CMC/CMCh (50/50) + 30wt% LiCH3COO reached a decomposition voltage around 2.54 V, while CMC/CMCh (50/50) + 10wt% LiCH3COO was decomposed at a lower voltage around 1.55 V. Based on the transference number measurement appeared that the initial and final current values of 0.84 for the CMC/CMCh (50/50) + 30wt% LiCH3COO is higher than that of the CMC/CMCh (50/50) + 10wt% LiCH3COO (0.8). Based on the results obtained, it can be concluded that the CMC/CMCh blend (50/50) + 30wt% LiCH3COO meets the minimum requirements for the main parameters of ion conductivity and thermal stability as a solid electrolyte polymer membrane but needs improvement and attention to its mechanical properties.Highlights CMC and carboxymethyl chitosan (CMCh) have polar groups for ionic conduction. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has good ionic conductivity of 2.24 × 10−5 S cm−1. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has high thermal stability 256–473°C. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has high decomposition voltage around 2.54 V. The CMC/CMCh blend (50/50) + 30wt% LiCH3COO has higher transference number (0.84).

Cellulose and its derivatives have been widely used in various applications. Cellulose can be isolated from sugarcane bagasse waste. This research aims to isolate and modify the sugarcane bagasse cellulose to improve its characteristics and usability. Cellulose was isolated using the alkalization and bleaching method, wherein the alkalization processes the biomass was immersed in a sodium hydroxide solution and bleached using hydrogen peroxide. Cellulose modification was performed using alkali treatment and etherification stages with monochloroacetic acid in an isopropanol solvent. The β‐(1,4)‐glycosidic vibration absorption on both the bleaching products at 896 cm−1 confirmed pure cellulose, while a carbonyl group at 1610 cm−1 in the modified cellulose product confirmed the pure CMC product. The CMC obtained had lower thermal stability in the interval 241.35–299.87 compared to cellulose as its source, indicating an increase in the amorphous region. According to experimental findings from the MB adsorption investigation, citric acid‐crosslinked sugarcane bagasse derivatives of carboxymethyl cellulose (CMC) were more effective adsorbents for removing MB than commercial CMC with the same formulation (2 : 1). The study‘s findings also indicated that an increase in the percentage of MB degradation was correlated with an effect of adsorbent dose and contact time.
