process for converting biomass to energy. Pyrolysis is the thermal degradation of dried biomass occurring in the absence of oxygen. A liquid product that is dark brown and proximate to biomass in elemental composition (bio-oil), char (biochar), and gases are produced from this process (Bridgwater, 2012). Lower

4. Eutrophication: rapid algal growth caused by an excess of nitrogen & phosphorus. 5. Hypoxia: when aquatic plants die, the BOD rises as aerobic decomposers break down the plants, the DO drops & the water cannot support life {note: DO = dissolved oxygen} 6. Primary Air Pollutants: produced by humans & nature (CO, CO 2 , SO 2 , NO, hydrocarbons,

decomposition of plant and animal material. During the later stages of eutrophication the water body is choked by abundant plant life due to higher levels of nutrients such as nitrogen and phosphorus. Human activities can accelerate the process with urban construction, sewage discharges, agricultural practices, and residential development.

DR/2010 Spectrophotometer. Algal biomass was estimated by using Chl a. Chlorophyll a (µg/l) was calculated after reading the absorbance at 665 nm and 750 nm. This was done after leaving the samples in a refrigerator for 23 hours in an extraction process using 94.1 methanol. The Chl a represents 1.5 % of the dry

The main intention was to explore, identify, and recover the functionalized chemical compounds formed from the algal remnant. Computational methods were used to estimate the solubility of one identified compound, 5-

If larger test portions are required, an instrument employing frontal chromatography can be chosen. The latter approach employs a GC column with thermal conductivity detection but provides a step-wise profile for integration.
