An active air sampler was used to trap polyaromatic hydrocarbons (PAHS) in the air above the sea area with massive oil spill. Air was pumped through an activated charcoal adsorbent material at a flow rate of 10 L per min for 12 hrs. The PAHs were then eluted out of the adsorbent material using 10 mL hexane. The eluate was analyzed by GC-MS. Anthracene was one of the PAHs detected and was found to be present at a concentration of 81.1 µg/mL. Determine the concentration of anthracene in the air above the oil spill. Report your answer in mg/m³.

2. Ferrous iron (Fe2+) must be removed from a steel plant wastewater to meet a pretreatment standard of 106 M. The proposed treatment scheme involves oxidizing the ferrous iron to ferric iron (Fe³+) in a CMFR. The ferric hydroxide precipitate (Fe(OH)3(s)) will be continuously removed from the bottom of the reactor to maintain steady state conditions. Dissolved oxygen will be added to the reactor by bubbling air through the solution. The pH in the reactor will be kept constant by the addition of a well-buffered caustic waste stream from another part of the plant. You are given the following information: Temperature=20 °C Waste stream flow rate Caustic stream flow rate = 1000 L/min = 100 L/min Concentration of Fe²+ in the waste stream=5x10-3 M Volume of reactor-72,500 L Saturation concentration of oxygen at 20 °C = 9.08 mg/L = 2.84x104 M Constant pH in the reactor = 9 Assume that there is no dissolved oxygen in either the waste stream or the caustic stream. The reaction occurs in two…

The two must be done independently of each other, as they are completely unlike. A qualitative analysis must always be done before a quantitative analysis. A quantitative analysis must always be done before a qualitative analysis. A qualitative analysis identifies the type of ion in solution and the quantitative analysis will determine how much of this ion is present. A quantitative analysis identifies the type of ion in solution and the qualitative analysis will determine how much of this ion is present. i 11:15
An analyst was measuring the performance of a HPLC column. The test solute was Toluene (5 µL). The column was a 4.6 mm i.d. column, 150 mm in length and packed with 5 µm C18 particles. The mobile phase was 40/60 water/methanol and the flow rate was 0.80 mL/min. The void time (to) was 1.86 minutes The retention time of the toluene sample was 14.50 min.

500 ml of wastewater sample was collected and 200 ml of this sample was analyzed by classical 5 day BOD test (at 20\deg C) with 1/15 dilution. The initial DO measurement result was 9 mg/L and 35% reduction in DO was observed at the end of the experiment. The BOD reaction rate constant was 0.24 d¹ (base e) and there was no change in the DO concentration of the blank. If this wastewater contains 2.35 mg/L ammonia, 0.073 mM nitrate, 0.66 mg/L. nitrite and 7.81 mg/L TKN, answer the following questions:a) What are the organic nitrogen and total nitrogen concentrations in this sample?b) Calculate the BOD, at 10\deg C.
