Abstract: A low-cost and efficient photocatalytic reactor for environmental treatment and green technology was presented. ZnO nanorods firmly growing on polycarbonate optical disk substrate are generally perpendicular to the substrate as the immobilized photocatalyst of the spinning disk reactor. The photocatalytic efficiency and durability of the ZnO nanorods are effectively demonstrated.

SUPERCRITICAL CO2 EXTRACTOR FOR SALE: 5L, 10L and 20L - 2,000 psi Complete Supercritical Fluid Extraction System - closed loop. Our systems are made at our fabrication shop in the state of Washington. Systems available: 5L, 10L, 20L, 100L, and larger custom. Typical build time is 2 weeks. This is not a Apeks Supercritical or Waters Supercritical CO2 Fluid Extraction System. We believe it is a better system, since we use 1/2 inch tubing for the CO2 flow, which is 4 times the flow rate of a Apeks, and up to 64 times the flow rate of a Waters system. We believe the result is faster processing time and better yield from increased exposure to CO2 solvent. Perfect for extraction of terpenes, trichomes, and Cannabinoids. Supercritical CO2 Fluid Extraction is a art, and the operator must have experience and training to obtain results. Go to website
