Hamburger seed coat is a readily available agricultural waste product generated in large quantities annually. In this study, activated charcoal was produced using hamburger seed coat activated with zinc chloride and its physicochemical properties such as fixed carbon, specific surface area, volatile matter, ash and moisture content were investigated. Scanning electron microscopy and Fourier transform infrared spectrometry techniques were used to study the surface morphology and variations in the absorption bands of functional groups, respectively. The adsorbent biosorption of pollutants abilities from contaminated water was investigated using standard methods with a view to ascertaining the adsorbent purification potential. The results showed that the adsorbent was of high porous structure with adsorption capacity significantly correlated with iodine value. The physicochemical properties of the contaminated water treated with the adsorbent were comparable with commercial activated charcoal (control)-treated water but indicated a significant decrease (p < 0.05) in the pH, temperature, total dissolved solids, total suspended solids, conductivity, turbidity, alkalinity, hardness, biochemical oxygen demand, chemical oxygen demand, anions and heavy metal ions when compared to the untreated water. With the exception of alkalinity, other parameters investigated in the water treated with the test adsorbent fell within the standards set for potable water. Results of this study therefore revealed possibility of converting large quantities of hamburger seed coat wastes that could constitute environmental pollution to a profitable product that could be employed for treatment of wastewater.

用源自汉堡包种皮的活性炭净化污染水的见解。

汉堡种皮是一种容易获得的农业废弃物，每年都会大量产生。本研究采用氯化锌活化的汉堡种皮制备活性炭，研究了其固定碳、比表面积、挥发物、灰分和水分含量等理化性质。扫描电子显微镜和傅里叶变换红外光谱技术分别用于研究表面形态和官能团吸收带的变化。使用标准方法研究了吸附剂对污染水中污染物的生物吸附能力，以确定吸附剂的净化潜力。结果表明，吸附剂为高孔结构，吸附量与碘值显着相关。用吸附剂处理的污染水的物理化学性质与商业活性炭（对照）处理的水相当，但表明 pH 值、温度、总溶解固体、总悬浮固体、电导率、浊度显着降低（p < 0.05） 、碱度、硬度、生化需氧量、化学需氧量、阴离子和重金属离子与未经处理的水相比。除碱度外，在用测试吸附剂处理过的水中研究的其他参数都在为饮用水设定的标准范围内。因此，这项研究的结果揭示了将可能构成环境污染的大量汉堡包种皮废物转化为可用于处理废水的有利可图的产品的可能性。补充信息 在线版本包含补充材料，网址为 10.1007/s13762-021-03577-8。
