Title : The Beer-Lambert Law and Its Limitation Objective : 1. To determine the linear relationship between absorbance and concentration of an absorbing species. 2. To study the effects of molecular dissociation complex formation on the applicability of the Beer-Lambert Law. 3. To investigate the derivation and limitation of Beer-Lambert Law. Introduction: In optics‚ the Beer–Lambert law‚ also known as Beer ’s law‚ the Lambert–Beer law‚ or the Beer–Lambert–Bouguer law relates the absorption

Introduction Climate change concerns to a statistically momentous deviation in either the mean state of the climate or in its variability‚ remaining for an extensive period (normally decades or longer) (What is climate change‚ 2001). Climate change is term that adverts to any major and long-term change in average weather in a specified region or whole Earth. Fundamentally important variability of average weather over longer time period can be depicted as climate change. Climate change is due to

Biodiesel production yields varied from 81.7 to 88.0 (wt%)‚ the lowest yields being the ones obtained using waste frying oil and lard alone as raw materials. The obtained products fulfilled most of the determined quality specifications according to European biodiesel quality standard EN 14214. Minimum purity (96.5 wt%) was closely obtained when waste frying oil was used alone and when 0.2% of lard was incorporated in the raw material (96.3 wt%); however‚ it ranged from 93.9 to 96.3 (wt%)
