Physico-Chemical Characterization of Wood Ash for Agronomic Purposes

Journal of Agricultural Chemistry and Environment 2024年第2期13卷 235-250页

作者： Ayi kévin Ajavon bassaï Magnoudéwa Bodjona diyakadola dihéénane Bafai Laboratory Waste Management Treatment and Recovery (GTVD) Faculty of Sciences University of Lome Lome Togo

The oil refinery of the food products company SOPAL, located in the port area of TOGO, produces an average of 200 kg of eucalyptus wood ash per day. This ash is stored in large quantities within the premises of the refinery, without any disposal solution. The aim of this study is to identify the physico-chemical properties of SOPAL’s wood ash for agronomic valorization. Physico-chemical analyses reveal the presence of major and secondary elements such as potassium (15.71 g/kg dM), phosphorus (27.90 g/kg dM), calcium (9.76 g/kg dM), magnesium (0.03 g/kg dM), sodium (1.24 g/kg dM), iron (1.49 g/kg dM) and manganese (7.82 g/kg dM). The pH is alkaline (12.97) with fairly high conductivity (24.10 mS/Cm). Heavy metals identified are cobalt (0.19 mg/kg dM), cadmium (0.10 mg/kg dM), lead (1.14 mg/kg dM), copper (19.77 mg/kg dM) and nickel (12.82 mg/kg dM). The results show that the ash contains considerable amount of major and secondary elements for agronomic uses.

Nano Copper ferrite Catalyzed Sonochemical, One-Pot Three and four Component Synthesis of Poly Substituted Imidazoles

引用

Modern Research in Catalysis 2016年第1期5卷 31-44页

作者： Paul d. Sanasi Ravi k. Majji Swathi Bandaru Satyanarayana bassa Surekha Pinninti Sruthi Vasamsetty Raghu B. korupolu department of Engineering Chemistry A. U. College of Engineering (A) Andhra University Visakhapatnam India

A simple, multi component, one-pot method has been reported for the synthesis of poly substituted imidazoles in presence of magnetically separable and recyclable spinel nano copper ferrite as heterogeneous catalyst by the cyclo-condensation of benzil, aromatic aldehyde, ammonium acetate and substituted amines under ultrasonic irradiation. This method of preparation has many advantages compared to those methods which are previously reported in the literature. This methodology offers simple experimental procedure, milder reaction conditions and environmentally benign approach.

A microwave irradiated magnetically separable nano cobalt ferrite catalyzed green method for the synthesis of 4-phenyl-4H-pyrano[3,2-h]quinolin-2-amine and 2-amino-4-phenyl-4H-pyrano[3,2-h] quinoline-3-carbonitrile derivatives through cyclization of aromatic aldehyde, acetonitrile/malononitrile and 8-hydoxyquinoline is developed and presented in this paper. The cubic magnetic cobalt ferrite nano particles were synthesized by sol-gel citrate precursor method and characterized by fT-IR, XRd, SEM and TEM techniques and the structures of the synthesized pyranoquinoline derivatives were assigned by IR, MASS and 1H NMR techniques. The reaction is carried out in a domestic microwave oven with a heat-resistant microwave safe glass container with a lid.

Cassava Peel Starch as a Raw Material for Polyhydroxyalkanoates Synthesis by Cupriavidus necator

引用

Open Journal of Applied Sciences 2024年第11期14卷 3127-3144页

Yao Patrick drogui Waste Management Treatment and Valorization Laboratory (GTVD) Faculty of Sciences University of Lom Lom Togo INRS Water Earth and Environment Qubec Canada department of Chemical Engineering-Nanomaterials Catalysis & Electrochemistry University of Lige Lige Belgium Houphout Boigny National Polytechnic Institute (INPHB) Yamoussoukro Cte dIvoire

The environmental problems caused by plastics of fossil origin are well known. To reduce harmful impact on the environment, bacterial-based plastics, such as polyhydroxyalkanoates (PHAs), are a promising solution. Microbial PHAs can be produced using abundant and inexpensive agricultural by-products as raw material. In this study, the potential use of Cupriavidus necator 11599 for the bioconversion of cassava starch into biodegradable PHAs was explored. Although Cupriavidus necator 11599 is a well-known PHA producer, it cannot grow directly on starch. Thus, acid hydrolysis was carried out on the starch extracted from cassava peels to obtain fermentable sugars. Optimal concentration of reducing sugars (RSs) was obtained by hydrolysis of cassava peel starch with sulfuric acid concentrations of 0.4 N and 0.6 N, at 95˚C and 4 h. The hydrolyzed starch was used for PHA production in Erlenmeyer flasks using reducing sugars (RSs) concentrations ranging from 10 g/L to 25 g/L. The best RS concentration 20 g/L and 25 g/L gave 85.13% ± 1.17% and 89.01% ± 2.49% of biomass PHA content and biomass concentrations of 8.18 g/L and 8.32 g/L, respectively in 48 hours. This research demonstrates that cassava peel starch as an inexpensive feedstock could be used for PHA production, paving the way for the use of other starchy materials to make bioplastics.
