“…Grafting of lignin on p(AA) network enabled the higher capacity of water absorption for different pH values. p(AA) hydrogel reached lower capacity of loading of pesticides and a cumulative release rate (50.06-68.42%) in comparison to the composite (84.27-91.23%) for 10 days [90].…”

Hydrogels represent three-dimensional networks of polymer chains that have the ability of absorption of a significant amount of water or biological fluid. A special group of hydrogels are copolymers which respond to changes of pH values and temperature. Desirable characteristics of temperature-and pH-sensitive hydrogels based on N-isopropylacrylamide and anionic comonomers for different applications, from pharmaceutical to the environmental one, can be designed by composition of copolymers. The presence of the amide and carboxyl group in the structure of these hydrogels enables their application as adsorbents in the processes of removing the pollutants from aqueous solutions. Hydrogels based on N-isopropylacrylamide and anionic comonomers represent desirable three-dimensional matrices for controlled and sustained release of agrochemicals and drugs in relation to temperature and pH of the surrounding medium. Hydrogels, as separation devices, perform the concentrating of compounds or microorganisms solutions by absorption of greater amounts of water. One more application of these copolymers is for immobilization of enzymes.

“…Composites with p(AA) hydrogel and wheat straw, i.e. lignin, were applied for the release of urea and pesticides [90,91]. In the work of Sun et al, p(AA) hydrogel and its composite with lignin was synthetized for its application for the cumulative release of pesticides paraquat, cyfluthrin and cyhalofop-butyl.…”

“…Lignin has been used in several applications in science such as antioxidant, asphalt, carbon fiber and related, board binder, polymers, dust control, paper, chemicals, battery, fuel, heat, grease, dispersants and agriculture [4]. In recent years lignin is widely developed as an environmentally friendly antifungal ingredient [2,5]. The high phenolic content of lignin is used to destroy cell membranes resulting in changes in cell permeability that would inhibit and impair the growth of fungal cells [6], denature cell proteins, wrinkle cell walls and disrupt the metabolic pathways of fungi [7,8].…”

The high lignin content in a waste of oil palm empty fruit bunch (OPEFB) can be utilized as an active compound in the preparation of natural pesticides. Lignin from OPEFB can be degraded into phenolic derivatives. The degradation of lignin was carried out by photooxidation using TiO2, which was synthesized directly from the ilmenite minerals. The success of TiO2-ilmenite synthesis was evidenced by the appearance of specific diffractogram peaks at 2θ = 25.5° for anatase TiO2 and 27.65° for TiO2 rutile. The ability of TiO2-ilmenite in lignin degradation was analyzed using UV-visible spectroscopy. Based on the analysis, it was known that the use of TiO2-ilmenite 0.3 g with radiation time of 20 to 30 min showed the highest degradation of 16.40-23.42 %. The degradation results were used to determine the antifungal activity of lignin from OPEFB. The results indicated that the high activity of lignin from OPEFB in inhibiting the growth of Fusarium oxysporum Schlecht with the highest clear zone diameter was 2.59 cm.

This study aims to obtain phenolic lignin derived compounds through the lignin degradation of oil palm empty fruit bunches (OPEFB) using TiO 2 photocatalyst and its antifungal activity against Fusarium oxysporum. The lignin degradation of OPEFB begins with the extraction and isolation stage using the soxhletation method with the presence of sodium hydroxide as a catalyst. The success of this stage is indicated by Gas Chromatography (GC) measurement of 4-vinylguaiacol and Fourier Transform Infra Red (FTIR) spectroscopy measurement that indicated the appearance of seven specific peak of lignin occurring at wave numbers 3421 cm -1 , 2929 cm -1 , 1596 cm -1 , 1508 cm -1 , 1462 cm -1 , 1041 cm -1 , and 875 cm -1 . This result is supported by the appearance of specific peaks of guaiacyl and syringyl groups at wave numbers 1328 cm -1 and 1220 cm -1 . Based on the variation of the degradation time, the lignin degradation of OPEFB with a degradation time of 15 min. showed optimum results in the production of lignin derived compounds. In addition, it also provides a strong inhibitory response to the growth of Fusarium oxysporum with a clear zone diameter 2.39 cm.
