摘要
在这项研究中,使用了一种新的方法来确定水中的铁含量,通过使用智能手机设备的颜色生物传感器作为生物传感器,通过下载到手机上的程序(颜色计)检查样品图像的颜色强度。样品的浓度是根据设备(Galaxy J7 prime 2)录制的视频的基本颜色(红、绿、蓝)(RGB)的值来测量的。移动设备的附件是用塑料(黑色丙烯酸)设计的。以暗盒的形式从内部安装有流电池和反射移动设备发出的闪光灯的镜子和与红色互补的绿色滤光片,以及通过耳机连接到智能手机设备的微动开关,设备通过设备外壳连接到附件上。该方法的校准曲线在mg/L(1 ~ 8)范围内,相关系数(R2) =(0.999),检出限为(0.2)mg/L,浓度的相对标准偏差(RSD%)为(4)mg/L,重复检测(10)次,其值为(0.6%),回收率(recovery %) =(101.5%)。
Novel Semi-Automated Design for Determination of Iron in Water using Smartphone Camera Complementary Metal-Oxide-Semiconductor (CMOS) Biosensor as a Detector Device
In this research, a new method was used to determine the amount of iron in water, by using the colour biosensor of the smart-phone device as a biosensor for the chromatic intensity of the samples images that are examined through a program (colour meter) downloaded to the phone. The concentration of the samples is measured from the value of the basic colours (red, green, blue) (RGB) for recorded video from a device (Galaxy J7 prime 2). An accessory for the mobile device is designed from plastic (black acrylic). In the form of a dark box from the inside equipped with a flow cell and a mirror reflecting the flash light emitted by the mobile device and a green filter complementing the red colour, and a micro switch connected to a smart-phone device via earphones, and the device is attached to the accessory by the device case. The calibration curve for this method was in the range of mg/L (1-8), the correlation coefficient (R2 ) was equal to (0.999), the limit of detection was in the amount of (0.2) mg/L, and the relative standard deviation (RSD%) for the concentration was (4) mg/L, for which the examination was repeated (10) times, and its value was (0.6 %), and the recovery value (Recovery%) was equal to (101.5 %).
