Abstract: An on-site detection device for nitrogen and phosphorus contents in liquid feces based on near infrared spectroscopy, including a box body, a box plate and a box cover, an independent detection part is formed, in which a detecting component and a sensor group are arranged; the detecting component, a temperature regulating component, a gas circulation component and the sensor group are all electrically connected to the controlling component, thus to achieve precise on-site detection. This disclosure utilizes a detection component to collect sample spectral information with 360°, minimizing the impact of temperature, humidity, and interfering gases in the detection environment with the assistance of temperature regulating and gas circulation components. This ensures accurate and stable spectral signal detection, thereby addressing the technical bottlenecks and weak stability in conventional laboratory chemical determinations.

Abstract: The present invention relates to a preparation method of La(OH)3 nanorod/walnut shell biochar composite material (LN-WB), comprising the following steps: putting walnut shell powder into a crucible and pyrolyzing and carbonizing in a muffle furnace at 350° C. to 450° C.; after the pyrolysis is completed, grinding and sieving the obtained biochar, and then repeatedly washing with deionized water; drying the washed biochar for later use; putting an appropriate amount of biochar into the deionized water to form a turbid solution; simultaneously dropwise adding LaCl3 and NaOH to the above turbid solution by using a peristaltic pump; and allowing the obtained mixture to stand at room temperature for 20 to 30 h, washing and drying for later use. The present invention successfully prepares a La(OH)3 nanoparticle-loaded biochar composite material through a simple synthesis technology.
