Abstract

The existence of dye molecules prolonged in water effluents of special concern is removed through green synthesized Punica Grantanum stem adsorbent (PGSA) embedded in removal of dye as methyl orange, Chromoseint blue, Eriochrome black-T, malachite green. Charcolated adsorbent was subjected to characterization as, SEM, TEM and FTIR. PGSA was employed in parametric study of effect of pH, effect of adsorbent dose on dye removal, effect of adsorbent on concentration of dye and effect of temperature on dye removal. Maximum removal of dye was observed at basic pH 8, as adsorbent dose of 0.5g give maximum removal of dye molecules. Maximum dye concentration of 1×10-5M show best result for dye removal and 30°C temperature was effective for various dyes giving removal efficiency. Experimental work was conducted on UV-Visible spectrophotometer with time gradient of 15 minutes time interval up to 180 minutes. So, this study revels use of charcolated adsorbent of Punica Grantanum stem is effective for dye removal purpose.

从罂粟根茎中提取的有色吸附剂的绿色合成及其在去除甲基橙、胭脂虫蓝、ERIOCHROME BLACK -T 和 MALACHITE GREEN 的染料中的应用

在去除甲基橙、Chromoseint 蓝、Eriochrome 黑-T 和孔雀石绿等染料时，通过嵌入绿色合成的石榴茎吸附剂（PGSA），可去除特别令人担忧的废水中长期存在的染料分子。对炭化吸附剂进行了表征，如 SEM、TEM 和 FTIR。利用 PGSA 对 pH 值的影响、吸附剂剂量对染料去除的影响、吸附剂对染料浓度的影响以及温度对染料去除的影响进行了参数研究。在碱性 pH 值为 8 时，染料去除率最高，吸附剂剂量为 0.5 克时，染料分子去除率最高。最大染料浓度为 1×10-5M 时，染料去除效果最好；温度为 30°C 时，各种染料的去除效率都很高。实验工作在紫外-可见分光光度计上进行，时间梯度为 15 分钟至 180 分钟。因此，这项研究表明，使用石榴茎炭化吸附剂能有效去除染料。
