Slow Release Urea

An environmental friendly slow-release urea fertilizer with double films (SUFDF) was prepared by using dialdehyde starch urea resin (DASU) as inner coating and polylactic acid (PLA) as outer materials. The structural, chemical characteristics and morphology of the SUFDF were characterized by FTIR, element analysis and SEM. Its efficiency in slowing the nitrogen release was examined via soil leaching and pot experiments. The experimental results indicated that the introduction of hydrophobic PLA and DASU reduced the swell ability of the fertilizer, which made it can provide nitrogen persistently at the early farming. After the urea dissolved, the DASU in the fertilizer would continue to release nitrogen due to its good slow-release property. So this fertilizer would have potential applications in modern agriculture and horticulture.

Purpose The purpose of this study is to provide effective and environmental-friendly corrosion inhibitors derived from graphene oxide for Q235 steel. Design/methodology/approach Nontoxic and environment-friendly 4-aminobenzoic acid was used to functionalize graphene oxide via amidation and diazotization. The obtained amidation 4-aminobenzoic acid functionalized graphene oxide (PAGO) and diazotization 4-aminobenzoic acid functionalized graphene oxide (PDGO) were characterized by FTIR, Raman and TEM, while the inhibition efficiencies were analyzed by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP). Furthermore, theoretical inhibition efficiencies were investigated by density functional theory (DFT) approach. Findings At a concentration of 40 ppm, the maximum inhibition efficiency of PAGO and PDGO were 97.90% and 96.72% in EIS measurement, respectively, which were in accordance with PDP data. Moreover, experimental results were supported by DFT-based quantum chemical calculation. Originality/value Environmental-friendly PAGO and PDGO were synthesized successfully. The synthetic inhibitors exhibited excellent inhibition efficiencies in EIS and PDP measurements. Furthermore, a computational study using DFT supported the trend that PAGO was better inhibitor than PDGO.

Kjeldahl Digestion

A kind of double-coated environmental friendly fertilizer was prepared by urea as a core, well-mixed keratin and oxidation starch as an inner coating, and superabsorbent polymer as the outer coating. The influence of water absorbency, water retention, and the slow-release behavior of the study fertilizer were investigated. 0.01M CaCl2 immersion extraction and Kjeldahl digestion method were used to measure the content of nitrogen. And the result showed that the nutrient release was 72wt% on the thirtieth day. This result corresponded with the standard of slow release fertilizers of the Committee of European Normalization (CEN) [1]. Keratin and oxidation starch were biodegradable polymer and nontoxic. Both the properties of the materials and the result of the slow-release behavior suggested a new kind of excellent, environmental friendly, slow-release fertilizer.
