Kinetic model studies of controlled nutrient release and swelling behavior of combo hydrogel using Acer platanoides cellulose

Muhammad Rizwan et al.

Summary: This study investigates the use of controlled release combo hydrogel (CRCH) as a means to improve nutrient availability and enhance plant growth in sustainable agriculture. The CRCH fabrication process involves cellulose extraction, incorporation with acrylic acid and n-isopropyl acrylamide, and the development of a 3D crosslinked polymeric structure. The findings reveal that CRCH exhibits controlled nutrient release behavior and has potential applications in agriculture.

Fluorescent chitosan-based hydrogel incorporating titanate and cellulose nanofibers modified with carbon dots for adsorption and detection of Cr(VI)

Qiuyan Luo et al.

Summary: A novel fluorescent chitosan-based hydrogel incorporating titanate and cellulose nanofibers modified with carbon dots was prepared to effectively detect and remove Cr(VI). The hydrogel showed a high adsorption capacity for Cr(VI) along with good sensing abilities, enabling quantitative detection within a linear range. Analysis revealed that the excellent sorption and sensing capabilities were mainly attributed to the porous structures and the modification of carbon dots.

Influences of cation valence on water absorbency of crosslinked carboxymethyl cellulose

Zhicheng Zhang et al.

Summary: The addition of superabsorbent polymers (SAPs) in soil can reduce water percolation and evaporation, but the salt-tolerance and repeating water absorbency (RWA) of prepared SAPs still need improvement. This study investigated the impact of cation valence on the structural variations of crosslinked carboxymethyl cellulose (CCMC), and found that higher addition of NaOH resulted in higher water absorbency due to the presence of more carboxyl groups. The introduction of polyvalent cations benefited the stabilization of carboxyl groups, but also hindered the swelling ability of CCMC53 samples, leading to lower water absorbency.

Synthesis of a novel superabsorbent with slow-release urea fertilizer using modified cellulose as a grafting agent and flexible copolymer

Zahra Mohammadbagheri et al.

Summary: In this study, glucose units in cellulose were oxidized to new units with aldehyde and ene groups, which were used to synthesize an eco-friendly superabsorbent. The created double bonds enhanced the network formation between cellulose and acrylic acid, while also improving the flexibility of cellulose. Results showed that the modified superabsorbent exhibited good water absorption, retention capacity, and slow-release properties, and promoted plant growth.
