    Studies on Chemical Effect and Feasibility of Biosensor for Arsenic Detection in Water.
    (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh., 2011-06) Parveen, Shahnaz; Yousuf, Prof. Dr. Muhammad Abu
    220 water samples of different Arsenic (As) -affected areas in Bangladesh have been collected for analysis. Of them 58 samples were from Sagordari village of Jessore. 53 from Koyra village of Kolaroa, 56 from Hajigong village of Chandpur and 53 from Arihazar village of Narayangonj district. Various water quality parameters such as, p1-I, conductivity, chloride, iron content, hardness and dissolved oxygen were analyzed using standard analytical techniques. The suitability of investigated water for drinking and other purposes was also analyzed comparing with standard values. As content for the 220 different water samples have been perceived in there different methods, i.e., Merck field test kit, ARSOlux biosensor and ICP-MS methods. To find out an easy, low cost and environmentally friendly method for As content in ground water three different methods have been adopted. A comparison has been made among the three different test methods. Effect of different water quality parameters on As test methods has been analyzed. The p1-I range has been found to 6.2-8.1. It is seen that most of the samples i.e., 88.6% are alkaline while those of 10.5% are acidic and only 0.9% are neutral in nature. It is seen that only 4.5% samples have conductivity values with in the limit of drinking water range. Rest of the samples has high conductivity values. Of which 78.6% samples have the conductivity (cy) values of 0.5
