Effects of Pesticide Case Study INTRODUCTION The Bago City is the rice granary of Negros Occidental. The farmers of Bago City are struggling because of the pest. They have decreased their production of rice because of the pest. Our goal of engaging this case study is to analyze and see the effect of the pesticide to the crops. We are to seek good and bad effects of these pesticides. We’re going to focus only on finding the effects of these pesticides so we can come up with a good report. By observing

Exp # 2 showed that the presence of the bacterium and iron oxide in the reaction medium (E-Sh-Ox) promotes the disappearance of endosulfan but inhibits its hydrolysis (and thus its transformation into ES-diol ) susceptiblement by more effective adsorption phenomenon. It is observed in this case 89.45% α + β O disappeared for 33.92% of ES-diol product‚ 56% of ES α + β missing. However‚ by amending formate (carbon source and electron) to medium (one obtains E-Sh-Ox-f)‚ the production rate in ES-diol

nitrogen flow with temperature range of 30 to 900 oC. The textural properties were determined using nitrogen adsorption/desorption isotherms measured with a Quantachrome Autosorb iQ instrument at 77 K. Before each analysis‚ the samples were evacuated for 3 h at 200 oC under helium atmosphere. The BET surface area was calculated by the Brunauer-Emmett-Teller (BET) method based on adsorption data in the relative pressure (Ps/Po) range 0.05-0.30. The total pore volume was determined from the amount of

Laboratory Exercise #2 Pre Lab This lab will teach me how to use a spectrophotometer. The use of the spectrophotometer is to measure the concentration of solute. The solute being measured must be colored and is determined based on the adsorption of light photons on a wavelength. The spectrophotometer uses a beam of light that strikes the diffraction grating that basically forms of prism of light. Then only a specific wavelength of light shines through the spectrophotometer and interacts with

Phase The mobile phase is the phase that moves through the stationary phase (explain that stuff). As the mobile phase is moving through the stationary phase‚ it picks up compounds that need to be tested‚ taking those compounds with it. Through adsorption‚ the mobile phase separates into different components (soinc). The mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid

2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

pores are used as the entrance to the activated carbon‚ the meso pores for transportation and the micro pores for adsorption. Different types of Activated Carbons can be produced with specific characteristics depending upon the raw material and activation technique used in their production . Apelsa CCA-700 activated carbons are products that feature high capacity for contaminants adsorption. Manufactured from coconut shell they present an optimum micropore volume‚ which is ideal for small molecules

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria

Immobilization of Enzymes And Their Applications By‚ Shudhangshu Shekhar Kundu Introduction: What an enzyme? Enzymes are protein molecules‚ which serve to accelerate the chemical reactions of living cells (often by several orders of magnitude). Without enzymes‚ most biochemical reactions would be too slow to even carry out life processes
