The importance of biosorption is soaring in the recent times owing to the cost-effectiveness, economical approach, good environmental impact, capability of being reused, safe degradation, and disposal of biological sorbents, among many other benefits. A major concern in today’s industrially and technologically advanced society is the harmful impact of toxic chemicals and dyes obtained as effluents from a variety of manufacturing industries, textile, and chemical industries, posing a potential threat to biotic life and the environment. Bio-sorption as a field for remediation of toxic chemicals and dyes has gained momentum where application of various kinds of bio-wastes obtained from agro-industries, natural textiles, animal wastes, sewage, and even biological remnants obtained from the paper industry are used for sorption of these harmful and toxic ionic salts, some of them being lead, hexavalent chromium, arsenic, bismuth, etc. Although biological materials are environmentally friendly, their application in large scale and as effective bioadsorbents needs much research to boost their performance as catalysts. This paper aims for testing adsorption capabilities of Pistacia vera in small scale application for the adsorption of methyl orange and methyl red, which are azo-dyes commonly used in the textile industries. A steady decline in the graphs for both the dyes proves the stability of the intrinsic physical and chemical properties of the pista nutshell for efficient removal of azo-dyes from water. Moreover, pista shells have intrinsic anti-microbial, anti-oxidant properties that naturally help remove free radicals. Though there are many physical processes of remediation of water, bio-sorbents are proving to be more cost-effective and economical, much of which can also be reused and remnants can be safely degraded and discharged. Thus, shells, kernels and other bioadsorbents can be beneficial in contributing curbing various environmental issues, provided instruments are devised to contribute on an industrial scale.
